Indian Railways Institute of Mechanical & Electrical Engineering (IRIMEE) is located at Jamalpur in Munger district of Bihar, on the Patna-Bhagalpur rail route, about 8 kilometres from Munger town. During the era of Mahabharata, Munger was the capital of Anga Pradesh ruled by Karna. Munger was also the seat of Mir Kasim, Nawab of Bengal, who fought the East Indian Company here. The place had traditional skills of making firearms, and hence selected by the East Indian Railway for one of its earliest workshops. The location selected was at the foothills of Rajmahal range (a part of Chhota Nagpur plateau), which was high enough to survive any threat of floods from Ganga, and the hills secured it against any organised attack from an army. The location had a tomb of Baba Jamal Saheb, after whom the place was called Jamalpur. Jamalpur Workshop was established on 8th of February 1862.
IRIMEE had humble beginnings, when it started in 1905 as a technical school attached to the Jamalpur Workshop. It came into national prominence when it started the training of Special Class Railway Apprentices as Mechanical and Electrical engineers, starting from the year 1927. In 1974, the school was made a Centralised Training Institute (CTI), renamed as Indian Railways Institute of Mechanical & Electrical Engineering, and brought under direct control of Railway Board. It is, therefore, the oldest of the CTIs.
In 1988, the training of IRSME probationers was centralised under the control of Director, IRIMEE but with HQ at Kharagpur, where there was an Officer on Special Duty (OSD) co-ordinating the training with the Director. From 1997, HQ of IRSME Probationers was shifted to Jamalpur
