Bangladesh Railway Class 6500 is a class of 1,676 mm gauge diesel-electric locomotives owned by Bangladesh Railway. There are 36 locomotives of this class, all manufactured by the Banaras Locomotive Works of India. All locomotives of this class are in service.^[1]

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 that stands for broad gauge (B), Diesel-electric (E), manufactured by DLW (D), 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 (B), Diesel-electric (E), manufactured by DLW (D), 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.
