There is a short report “Afghan railway progress” on page 91 of the January 2010 issue of The Railway Magazine.
This mentions the Asian Development Bank funding, and describes the Iran to Herat line as “stalled due to both lack of resources and border disturbances”. It reports there are 20 wagon loadings a week to Towraghondi, and 30 daily to Hayratan.
The Railway Magazine of May 1928 (p410) has photo of the “Time-table of Royal Train in English and Persian” for the King of Afghanistan’s visit to Swindon works, G.W.R. On March 21.
GREAT WESTERN RAILWAY
The Journey of Their Majesties the
King and Queen of Afghanistan
From Paddington to Swindon
On Wednesday, March 21st, 1928.
More details of King Amanullah’s tour of Europe, with some wonderfully fawning quotes from Railway Gazette. On his peregrinations he also visited Berlin in March 1928, where he went for short ride on – and was allegedly invited to drive – one if the then-new A2 small-profile U-bahn trains, leading to the type becoming known as the “Amanullah-Wagen”.
The March 2008 issue of Majesty magazine has an article:
Roaring Twenties: A compelling account of the King and Queen of Afghanistan’s state visit to Britain, by Russell Harris. When I get chance to pop into one of WH Smith’s public reading rooms I’ll see if there is any railway content.
