[1][2] A locomotive, carriage, and wagon workshop had been set up in Howrah to put imported rolling stock into service for the EIR and also to carry out repairs.
The school attached to the Jamalpur workshops eventually became the IR Institute of Mechanical and Electrical Engineering.
When the selection was made it was probably thought that Jamalpur would be on the proposed mainline of EIR which was subsequently changed and was directed to Delhi via Ranigunj, Gaya, Mughalsarai, Allahabad and, Kanpur.
Initially, Jamalpur was only an engine changing station and, light repairs were done in the running shed there.
The original headquarters of the locomotive department of EIR was situated at Howrah but had a great drawback because it was too confined for extensions as and when needed.
At Howrah, the original workshop was supposed to handle the building of locomotives, carriages and wagons.
The following are some of the preserved locomotives built by Jamalpur locomotive workshop marked as JMP: The Indian Railways Institute of Mechanical and Electrical Engineering (also known as IRIMEE) at Jamalpur is the oldest of the Centralized Training Institutions (CTIs) of the Indian Railway.
After the first World War, the technical school was greatly expanded for the taining of railwroadapprentices and supervisory staff involved with mechanical engineering.
In the 1960s, a Diesel Traction Faculty was set up to conduct training courses and publish educational materials as IR engaged in desalinization.
The Jamalpur jacks have been gaining in popularity chiefly due to low initial capital investment and minimum maintenance needs.
It is worthwhile to mention that the performance and cost factor of these jacks have posed a serious challenge to capital intensive electrical overhead-traveling cranes.
Besides Indian Railways, these Jamalpur jacks have been operating successfully at various steel plants and allied industries.
