In the early days, Class 2000 locomotives were heavily used for prominent Bangladeshi trains like Ulka Express, Mohanagar Express, Parabat Express etc. Currently, class 2000 locomotives are being used for freight trains. Due to several mechanical constraints, they are not used in passenger service unless an emergency situation occurs. The Class 2000 locomotive is considered a lifeline for freight services of Bangladesh Railway. It pulls containers, oil tankers and other departmental freight  trains regularly across the country. Maintenance. The Class 2000 Locomotives are maintained by Diesel Workshop at Pahartali, Chittagong. These locomotives are not allowed to cross Bangabandhu Bridge due to mechanical restrictions. Therefore, they cannot go to Central Locomotive Workshop (CLW) at Parbatipur, Dinajpur for maintenance.
