The Carriage Repair Workshop, Harnaut provides bogie maintenance services for India's East Central Railway.

East Central Railway had no carriage repair workshop and was totally dependent on ER and NER.

President APJ Abdul Kalam had laid the foundation stone for the workshop at Harnaut on 30 June 2003, during Nitish Kumar's tenure as railway minister.

There are five departments dealing with various activities such as Mechanical, Electrical, Materials Management, Finance & Accounts, HRD, Audit & Security.

According to project in-charge Sunil Kumar, the railways has installed machines, including bogie testing apparatus, surface wheel lathe, plasma profile cutting machines and other essential plants required for smooth functioning of the workshop.
