The workshop had carried out several innovations and fabricated machines, gadgets and fixtures for streamlining production process and improving the productivity.
It also repaired about 25,000 wheels and 10,000 LB springs annually and undertaken repair work on wagons and wheels owned by the NTPC and other companies.
