Steam locomotives were in service when rail network started in the then East Bengal of Indian Subcontinent on 15 November 1862. They were the dominant type of locomotive of that time and even with the introduction of diesel powered locomotives in 1953, they served the railway of Bangladesh till the '80s. Currently no steam locomotives are in operation. Most of them has been scrapped. A small number of them are preserved in Bangladesh. Here are some steam locomotive classes that were operated by EBR/PER/BR:
Narrow-gauge (762 mm)
The gauge locomotives are from the Rupsa-Bagerhat railway which was the only gauge line inEast Pakistan when colonial India was partitioned in 1947. It was re-gauged to gauge in 1970.
Class CB
These locomotives were manufactured by The Vulcan Foundry Ltd., England. They were withdrawn in 1970. Two units are preserved, CB7 at Paksay Railway HQ, Iswardi, Pabna with an attached coach behind and CB8 at Pahartoli Workshop, Chittagong.

Diesel locomotives first started operation in Bangladesh with the introduction of Class 2000 EMD B12 diesel-electric locomotives in 1953. Till now, 445 diesel locomotives have been imported over times in Bangladesh, including 80 diesel-hydraulic locomotives. Among them, 317 are meter-gauge and 117 are broad-gauge locomotives. There may also exist some narrow-gauge diesel locomotives in Bangladesh but there is no adequate information regarding them. Among the 445 locomotives, 273 locomotives are currently active, including 179 meter-gauge locomotives and 94 broad-gauge locomotives. Among them, 140 meter-gauge locomotives and 55 broad-gauge locomotives have reached expiry within times. Only three diesel-hydraulic locomotives are active and the rest are all diesel-electric.
Classification and numbering of locomotives
In Bangladesh Railway, the present 'classification' or 'specification' of locomotives has three letters with two digit number: First letter: Denotes the track gauge the locomotive is operated. Second letter: Denotes type of diesel traction. Third letter: Denotes first or last letter of the name of manufacturer. Two digit number: Denotes the approximate power * 100 of the locomotive in hp. For example: MEG-11, Here M = Meter-gauge, E = Diesel-electric, G = General Motors and 11 = 11×100 hp = 1,100 hp. In case of numbering of a locomotive, a four digit number is used. First two digits denotes the 'series' or 'class' of the locomotive and the rest two digit denotes the number of the locomotive of the respective series. For example: locomotive number 2025 means it is the 22nd locomotive of class 2000. Meter-gauge locomotives start with 2000 and ends in 3400 as of 2020. On the other hand, broad gauge locomotives start with 6000 and ends in 7000.

Class 2000
Class 2000 were the very first diesel-electric locomotives of the them Eastern Bengal Railway. They started service from 1953. Total 40 units were imported from General Motors. They used to haul long-distant passenger trains. Still 7 units are currently in service as of 2020.
