Details

Diesel Locomotive Works, India reconditioned and modified 10 of their YDM-4 locomotives from hood unit to dual cab unit similar to Class 2700 locomotives, and marked as YDM-4BR, and exported to Bangladesh Railway in 1996.[6] They have much similar specifications to YDM-4 locomotives of Indian Railways and Class 2300 and Class 2400 locomotives of Bangladesh Railway.

Usage

Class 2800 initially hauled many inter-city trains like Jamuna Express, but shortly were taken out from that service. They now only serve local and short-distant commuter trains. They are not used on freight operations.
