Kuala Lumpur monorails

Some notes on the KL and Putrajaya monorails. The text is now somewhat out of date!

Kuala Lumpur’s 8.6 km monorail finally opened in late August 2003. The line uses the straddle principle, with cars sitting astride an elevated concrete guideway.

The RM1.18bn line starts at Pekeliling bus station in the north of the Malaysian capital, near Titiwangsa station on the Star metro. It runs along the median strip of the city’s roads, passing in an arc through the east side of the ‘Golden Triangle’ central business district.

There are 11 stations, between 600 and 1 000 m apart. Bukit Nanas station is a short walk from Dang Wangi station on the Putra automatic metro, though there is a busy road in between. There is another interchange with Star at Hang Tuah. The southern terminus is KL Sentral mainline railway station, in the Brickfields area of the city.

The 19 minute end-to-end journey will cost RM2.50. Up to 20 000 assengers/hour can be carried, and services will run from 06.00 to midnight. There will be a train every 3-5 min at peak times, and 5-10 minutes off-peak.

Work on the monorail began in 1997. The technology was to have been imported from Japan, where a number of monorails in are in operation. Then the 1998 Asian economic crisis hit, and the resulting huge increase in the cost of imported trains meant the project was no longer viable. To revive the partly-complete scheme it was decided to use home grown technology, and work was resumed in July 1999.

KL Monorail System Sdn Bhd, formerly KL PRT Sdn Bhd, is the project’s promoter and operator. A subsidiary of MTrans Holdings Sdn Bhd, it has a 40 year government concession to build and operate the line, signed on 15 January 2001. To ensure financial viability KL Monorail System has rights to associated business activities. These include advertising and the development of Jalan-Jalan, a 250 000 sq ft riverside landscaped leisure development in Brickfields, with about 50 restaurants.

The company also owns manufacturer Monorail Malaysia Technology Sdn Bhd, which is marketing itself as a turnkey monorail supplier. MMT has a factory on a 22 acre site in Rawang, north of Kuala Lumpur, including a 1 km test track.

One of the alleged advantages of a monorail is its low footprint, requiring a narrower structure than a conventional elevated light transit system. “The monorail blends in well with modern urban environments and easily fits into a city” claims Monorail Malaysia Technology. Perhaps in a very modern architectural environment, such as KL, it will.

The guideway uses over 600 individually precast post-tensioned concrete beams. These have an average weight of 100 tonnes and length of 28 m. The top running surface is 0.8 m wide. The largest beams are 44 m long, weighing almost 190 tonnes. Almost every beam is unique. They were cast at the factory in Sungei Long, and cured for a minimum of seven days before erection. Ten different moulds were used, producing beams from straight to 65 m radius. Beams are 2.2 m deep at the ends, 1.6 m deep in the centre, and have up to 12% super-elevation. Tolerances are very stringent, +/-3 mm for the cross section width and +/-8 mm deviation from alignment in 20 m. The infrastructure is designed for a life of 100 years. A power rail is fixed to either side of the beam.

The beams are 10 m above ground level and supported on 284 columns. Cast in situ, these are set 30 m apart and measure 1.2 m x 1.6 m or 1.55 m x 2 m. Columns were positioned so as not to obstruct road users’ visibility, and a large arched bridge used to span a major road junction. Some short sections of pavement and road had to be realigned. Underground pipes and cables had to be avoided, and this was complicated by the lack of detailed records of what was present, resulting in an extensive programme of trial pit excavation and exploration. Once it had been determined what, if anything, was below the surface services could be relocated or planned column positions adjusted. To minimise road congestion on the crowded city streets the beams were delivered at night.

The maximum gradient on the mainline is 4%, and in the depot 6%. Minimum curve radius on the main line is 70 m, with 50 m in the depot. Minimum vertical curve radius is 1 000 m.

The stations are approximately 22 m wide and 65 m long, supported on columns in the road median, spaced at 13, 12 and 13 m. Access is by escalator, but stations are designed so lifts can be retro-fitted if accessibility legislation is brought in. Each station has ticket vending machines and sales counters, public toilets, telephones and sales kiosks.

The first of the locally-built trainsets arrived in Kuala Lumpur on 18 April 2002. The trainsets comprise two 10.4 m long head cars, with up to ten 8.6 m intermediate cars. All cars are 3 m wide, and 4.5 m high, with two 1.25m doors per side.

The trains are gangwayed throughout. Bodyshells are stainless steel, aluminium and composite, mounted on a steel chasis. Air cushion suspension is used, and the maximum axle load is 10 tons. There are four pneumatic-tyre load wheels per car, on single-axle bogies. While the old joke, perhaps inspired by the Lartigue system of Listowel & Ballybunion fame, about a monorail being ‘a railway which requires more then two rails’ does not apply in Kuala Lumpur, the carriages do have additional wheels bearing on both sides of the guideway in addition to the top.

[Monorail under construction]

The trains are designed for a maximum speed of 90 km/h, with a planned maximum service speed of 80 km/h and average speed of 30 km/h. In the event of a train failure passengers can be evacuated to a rescue train using a bridging plate.
My room on the 18th floor of the Renaissance Hotel overlooked the site of Bukit Nanas station. In the morning one or two works trains would arrive carrying construction materials. These have flat decks, with red pagoda-style structures on top.

Union Switch & Signal is supplying signalling, communications and SCADA for the line. The trains have radio-based in-cab signalling. Dual redundant Microlok II interlocking is used, with radio-based train location and detection, and Automatic Train Protection. The trains are driven manually, but upgrading to driverless Automatic Train Operation is possible.

Putrajaya Monorail

Support columns for the partly-elevated monorail line being built at the new federal administrative capital city of Putrajaya.

Putrajaya is the federal government’s new administrative capital city, being built on a green-field site 20 km from Kuala Lumpur. A light rail system was planned for the lakeside garden city, and some infrastructure work may have started, but then a change of plan was announced. It was decided to opt for a monorail, using equipment supplied by Monorail Malaysia Technology.

Putrajaya will have two monorail lines, which are planned to open in 2004. One will be 12 km long, with 17 stations. The 6km second line will serve six stations. The track will be elevated on the lakeside, and when I visited in March 2002 support columns for the monorail had been installed at the Express Rail Link mainline railway station. Unusually for a monorail, on Putrajaya’s central island in the lake the line will be underground.

There is lots more information about monorails on the website of the Monorail Society

A ride on Kuala Lumpur’s railways

A few pictures showing railways in and around Kuala Lumpur which I took in March 2002. Please note that the text is now somewhat out of date.

Kuala Lumpur seems to be trying to collect as many forms of rail transport as possible, with a conventional metro, an automatic metro, two different railway gauges and a monorail!

KTMB

The KTM Komuter network is centred on Kuala Lumpur. Electrification began in 1995, and 160 km is now wired at 25 kV 50Hz AC. EMUs run from Seremban, south of KL on the main line to Singapore, to Rawang in the north, taking two hours. The second Komuter route provides Sentul to Port Klang services, which take about 1·5 hours.

Both routes pass through KL Sentral and Kuala Lumpur stations in the capital city, and run regularly from about 05.30 to midnight.

[Station]
The old station building in central Kuala Lumpur dates from 1886.

[Station]
To the north of and contiguous with the old station are more modern facilities, where all the train seemed to be stopping. The old station has a train shed and open access to the platforms, the new has substantial canopies and automatic ticket barriers controlling access. Platform heights vary between the parts. There is another new station, KL Sentral, to the south.

Books

The Industrial Railway Society book The Spurn Head Railway (IRS Record 67) by KE Hartley (1976) covers the history of the line. There have been at least two editions, but it is quite hard to find.

Sailing the Rails – A New History of Spurn and its Military Railway by Howard Frost is a more recent 80-page book with delightful photography highlighting the story of a four-mile railway along the sand dunes of Spurn. Between 1915 and 1951 it linked two military forts and provided a lifeline to the mainland, for one of the most isolated lifeboat communities in the country according to the East Riding Council. I’ve got a copy of the book, and it is excellent. It is far more than simply an update of the previous volumes, and as well as the railway matters has more on the social history of Spurn and Kilnsea. If anyone is interested in the line or the area it is well worth acquiring a copy from the Butterfly Conservation Yorkshire Branch(!), even if you have one of the previous ones. There are a lot more pictures, and more details of military matters. My only complaint is that the text has too many “!” for my personal taste…

The September 1978 issue of Railway Modeller magazine had a plan for a model railway layout based on Spurn.

A visit to the Harzer Schmalspurbahnen

Some (rather badly scanned) photographs I took while on holiday in Germany in July 2003, along with an article I wrote for Eagle, the journal of the Cambridge University Railway Club.

[Steam loco at water crane]
99 7238-1 takes on water at Drei Annen Hohne. 2003-07-18.

The famous Harz narrow gauge railway network is operated by Harzer Schmalspurbahnen GmbH. Owned by the various local authorities, it still provides scheduled steam services on the 131.24 km network, which became the first non-federally owned railway in the former East Germany on 1 February 1993. HSB declares its aim as to “preserve all three railways in the Harz region in their entirety as a tourist attraction, a monument to engineering, a facility for freight haulage and as a local transport facility”. HSB has 25 steam engines, six railcars, and 16 diesel locos.

We began our July 2003 visit to the Harz in Wernigerode. An attractive town, it looks rather like a German theme park might be built, with brightly-painted and half-timbered buildings. The Harz railways station is, as so often in Europe, located just outside the main station. Stepping off our DB train we could see smoke rising in the distance, but the DMU from Halberstadt had been 44 minutes late, so out priority was finding the Youth Hostel.

The hostel was a surprisingly respectable place, though a bus ride from the town centre, and not as well sign-posted as it could be! From the window of our room it was just possible to see passing steam trains through the trees. Dumping our bags we headed into town for dinner in the restaurant under the Rathaus – being a major tourist centre, there are plenty of dining options in the town. We wandered over to peer over the fence at the railway sheds, and bumped into a local who explained all about what Bismarck did in the dramatically-sited castle, but sadly our German wasn’t up to it.

The next morning we headed into town to photograph the 08:44 departure from Westerntor station cross a large level crossing outside the western gate to the town centre. We then walked to the main station to acquire tickets. The staff were well used to tourists, and with schoolboy-German and pointing at the map we were soon sold a suitable ticket. This was a €24 BrockenCard, valid for one return trip from any HSB station to Schierke and Brocken, and one other, non-Brocken, return trip within three days. A three day rover ticket costs €35, 5 days €40 and 7 days 50.00. Dogs under 20cm high go free, but bigger ones are half-fare.

We caught the 09:25 from Wernigerode to Brocken, hauled by 99 7238-1, and very busy with German holiday makers. The trains are formed of balcony carriages of a design common to the former-DDR’s narrow gauge lines. Riding on the balcony was popular, but Germans are averse to open doors. One chap held his nose to point out that the carriage might start to smell of steam if the door was left open, and leaving us to wonder why he was sat in the front carriage. It was clear that some of the Germans found their own insistance on keeping the doors close rather amusing, and they were slightly theatrical in closing doors after returning from trips to stand on the balcony!

[Loco in the mist]
The loco runs round its train at Brocken station, 1125 metres above sea level. 2003-07-18.

The train arrived at the 1125m high Brocken station at 11:07, disgorging its passengers into the misty and slightly cooler surroundings. There is the typically German collection of sausage sellers, a restaurant and a hotel at the top of the 1142m high hill. The former military listening post is now a visitor centre with information on the national park, local wildlife and history. We bought postcards, but didn’t pay the €4 go in. There is a ban on using the train toilets between Schierke and Brocken, and we soon began to wonder if this was anything to do with charging people €0.50 for the ones on the hilltop! We wandered over to the railway to photograph 99 7242-3 hauling the 11:52 arrival, before boarding for the 12:08 back down.

[Steam loco in trees]
2-10-2T locos 99 231 to 99 247 were built at Karl Marx Locomotive Factory in Babelsberg in the 1950s for use on the narrow-gauge Eisfeld – Schönbrunn, Gera-Pforten – Wuitz – Mumsdorf, Harzquer and Brocken lines. Carrying its former DR number, 99 7234 is heading up to Brocken, while the downhill train waits in the passing siding. Once the uphill train has passed, the downhill train reverses out of the siding back onto the main line, then heads forwards to Schierke. 2003-07-18.

Halfway to Schierke the downhill train runs into a siding, where it waits for the uphill train to pass. The downhill train then reverses out of the siding, before heading forwards again. Throughout the journey staff wandered up and down the train with baskets, selling small bottles containing some form of alcoholic beverage.

We got off at Schierke, to watch the trains pass and grab some currywurst and bottled black beer, and be impressed by the range of tacky witch-themed souvenirs in the station shop (the German witches who apparently meet on the Brocken seem to wear a lot less clothing than British ones!). We then took the 13:40, seven coaches and a van hauled by 99 7234-0, down to the junction at Drei Annen Hohne, where the station features a beer garden, and there is a tourist information centre. After 15:00 we had the now unusual sight of three scheduled steam trains waiting to depart in three different directions.

The loco from the Eisfelder Talmühle – Wernigerode train, which includes an open wagon fitted with seating for which a supplement is payable, is swapped with the loco from the Brocken – Nordhausen train. The Wernigerode – Brocken train keeps its loco.

At 15:33 we set off for Nordhausen behind 99 7236-5. At Elend there was a slight pause as the station cafe supplied mugs of drinks for the loco crew.

The countryside is heavily wooded, and many trees later we arrived at Eisfeld Talmühle, junction of the two routes. A diesel railcar connection arrived from Nordhausen and went off towards Steige. The station building seemed to be under reconstruction, and there was a collection of freight rolling stock in DR livery stood in a siding. We passed through Ilfeld, the northern limit of a more frequent service which provide about one railcar an hour to Nordhausen, but at irregular intervals.

Nordhausen – closed for rebuilding

[Railcar]
There is short link between the HSB lines and the tramway in Nordhausen, allowing railcars to serve Nordhausen Nord, the bus and tram stop.

187 016-1 is one of four diesel-hydraulic railcars built to reduce costs on Alexisbad – Nordhausen Nord services and to provide school and commuter services between Ilfeld and Nordhausen. Partly paid for by the states of Thüringen and Sachsen-Anhalt, the 50km/h railcars were built at DB’s Halberstadt works and delivered from March to August in 1999. The design was developed using experience gained with prototype vehicle 187 015 which had been built in Wittenberge in 1996. (Photo 2003-07-18).

The HSB terminus in Nordhausen, just to one side of the DB station, gives the distinct impression of having seen better days. The one modern feature among the decay is the provision of a short link between the HSB and the town’s tram network. Branching off the HSB just before the station, this allows the HSB railcars to access the bus and tram stops in front of both railways’ stations.

The tram network comprises two lines electrified at 600 V DC. The 3.22 km Line 1 runs from the hospital in the north to the station in the south, the 4.55 km Line 2 runs from Parkallee in the northwest to Nordhausen East, crossing Line 1 in the town centre. During our stay much of the city centre was being dug up for rebuilding, and instead of serving the station via a large loop around the block the trams were terminating in a construction site a few minutes walk away.

The tramway was obviously having serious money spent on it, with some of the stops being modernised to light rail standards. In 2002 the town ordered 3 dual-mode Siemens Combino trams with 180 kW diesel engines, and from May 1 2004 these will operate an hourly service on a new Route 10 from the hospital, through the town centre and then under diesel power over the HSB lines to Ilfeld. We noticed that the southern end of the HSB also had very modern platforms, perhaps in readiness for the integration with the tramway.

[Tram]
Three-section Siemens Combino tram number 105 tram negotiates the road and tramway rebuilding works in central Nordhausen. The tramway is operated by Stadtwerke Nordhausen. (Photo 2003-07-18).

The city has a fleet of 7 Siemens Combino trams, a mix of uni- and bi-directional models. No. 107 was carrying vinyls referring to the tramway in the Austrian town of Gmunden where it had recently been demonstrated. Only having doors on one side of most of the trams was awkward in the city centre, where rebuilding of the southbound track meant all trams were using the other line, making the doors inaccessible from the platform.

Tickets are bought from machines on board the tram, which seemed to be quite new as some locals were struggling with it. While we debated whether it was worth getting a four-journey ticket, a local thought we were confused and came to offer help. Then the tram stopped, luckily on a reserved track section, and the driver came back to join in!

The youth hostel is one stop from the northwestern terminus of Line 2, but within walking distance of the town centre; the tramway really is tiny. Outside the hostel were two sidings in a locked compound containing older trams, now displaced by the Combinos.

Like so many towns Nordhausen was devastated by air raids in WWII (V2 rockets were produced in a nearby labour camp), was perhaps unsympathetically rebuilt, and is only now being restored; it is quite odd to see a section of medieval city wall being built! The whole town gave the impression of being shut for rebuilding. We ate at a cheap bar round the back of the Rathaus, which was the only sign of life we could see. We weren’t unduly disappointed to be leaving Nordhausen the next morning, but I think it will be a reasonable place once they have finished building it, though with few attractions other than its transport network.

Down the pit

At 10:06 the following day we set off for Netzkater behind 99 7236-5. We had planned to change trains one stop further on at Eisfelder Talmühle, but on the way in we had spotted a mining museum with a collection of narrow gauge rolling stock, and a beer garden.

A tour of the mine was departing as we arrived at the museum, and after relieving us of €5 the ticket office simply gave us hard hats pointed towards the drift entrance. We dashed down after the tour group, for a 45 minute walk around the disused coal mine. The tour was in German, but if you have ever done a tour of a mine you can work out much of what was being said and fill in the gaps! Part of the tour is completely unlit, visitors having to feel their way forwards through the tunnels. There was a demonstration of a cable hauled incline inside the mine, then we returned tot he surface, where for €0.50 rides on a 60cm gauge man-rider train were available. A beer later we caught the 12:10 diesel railcar for Hasselfelde on the Selkatal line.

Limitations of GCSE German

All but one of the other passengers disembarked at Stiege, but we continued to Hasselfeld. The ‘genuine’ passenger left, and the driver retired to the station cafe. We wandered around the station yard, where a steam loco boiler is on display. A shed contains another loco, which we think is privately owned and non-operational. We then returned to Steige, where the passengers who had got off earlier got on again! There were now 13 passengers,and the other 11 seemed fairly genuine, rather than simply there for the ride. In contrast, all seven or so coaches of the trains on the Brocken line had been pretty full.

de-brocken1-small.jpg

Numbers had thinned to four by Siberhütte. As we approached the station a stout gentleman in a bright pink shirt could be seen rushing towards the station, followed by a snaking line of 10 hikers. Unfortunately the train left the station before he made it to the platform. This left us with a problem, as I was off school during the “bang on the cab door and tell the train driver he had left the passengers behind” module of GCSE German. We pointed out to the other two passengers what had happened, and after some hesitation they went to establish communications with the driver. We stopped some distance beyond the station, and I hung out of the window to wave and shout at the hikers, who came trotting along the track behind us to catch up.

We got off at Alexisbad, the junction for the Harzgerode brach, and took the change to sample the local apple wine. A steam train arrived from Gernrode, and we caught it up the steeply graded branch. Many of the passengers seemed to be enthusiasts, and there were a few British people on board. A the terminus there was just time to glance into the castle courtyard, then it was time to head back down to Alexisbad, and change for a steam service to Gernrode.

The station area at Gernrode cannot be considered one of Germany’s greatest scenic delights. After ascertaining that the semi-derelict structure opposite the HSB terminus really was the DB station, and inferring from the presence of another, local-looking, passenger that there might really still be a train service, we had the best part of an hour’s wait for our two-car DMU. This took us to the very attractive town of Quedlingburg, which has an impressive gothic-style station, and a centrally-located – and this time well sign posted – half-timbered youth hostel where we were given a room in the attic.

Visiting

The Harz railways are well worth a visit. Wernigerode is geared up for tourists, and the Brocken line is very popular. The use of steam over the whole system can feel slightly “preserved”, but I felt the Selketal line had a slightly more genuine feel to it, with real passengers, and the railcars certainly provide a real service.

The one thing to beware of when planning a trip is that south of Drei Anne Hohne the trains are not very frequent, with four services per day over some stretches of line. The pattern of through trains is quite complex, and a trip over the whole network does require some planning.

HSB’s official website at gives full timetables, details and histories of the lines, and enthusiast oriented information on the rolling stock in both German and English.
