The Asian Development Bank has published an article Innovative Project Management and Coordination Speed Up Afghanistan Railway Project. This describes how the Hairatan to Mazar-i-Sharif line was “completed in record time” – basically by building on existing plans, awarding a turnkey contact, and chucking plenty of money at it.
The January 2014 article, Issue 51 in ADB’s Knowledge Showcases series, is by Balabhaskara Reddy Bathula, senior transport specialist at ADB’s Central and West Asia Department. He was the project officer involved in the entire process, from technical assistance processing to construction and “operationalizing” of the line.
