Details

In 2012, Bangladesh Railway ordered broad-gauge diesel-electric locomotives from India, modeled as WDM-3A. These 26 locomotives were imported in Bangladesh in 2012, 2013 and 2014.[2] These locomotives have a power of 3100 hp, the highest for any locomotives in Bangladesh. They are fitted with AAR coupling and have a gear ratio of 65:18.[3] These locomotives are marked as BED-30, which stands for broad gauge diesel-electric manufactured by DLW, engine with 30 * 100 hp (30) and numbered as 6501 - 6526.

On 27 July 2020, 10 WDM-3D units were imported from India marked as BED-33.[4][5] The class name stands for broad gauge diesel-electric manufactured by DLW, engine with 33 * 100 hp (33) and numbered as 6527 - 6536. These locos have a 3300 hp power pack, with maximum available traction power of 2925 hp.[6][7]

Liveries

Class 6500 locomotives have the deep blue-yellow and sky blue-yellow livery. BED-30s have the deep blue-yellow livery and BED-33s have sky blue-yellow livery.

Usage

Among all the class 6500 locomotives, BED-30 is basically used on both freight and passenger trains. Most high-end broad-gauge passenger trains like Padma Express, Banalata Express and Maitree Express are hauled by these locomotives. They are also used on some mail-express and commuter trains. On the other hand, BED-33 is usually only used on freight trains.
