HISTORY OF WORKSHOP GORAKHPUR 1. Gorakhpur workshop was established in 1903 for repair and overhauling of MG steam locomotives, coaches and wagons. 2. Due to gauge conversion from MG to BG, POH activity of 50 BG coaches/month was started in Sept 1984. 3. The POH of MG coaches was also stopped from January 2002. At present, this workshop is mainly carrying out POH of BG AC and non-AC coaches. 4. Capacity augmentation and modernisation Project Phase-I (costing Rs.22.7 Cr.) and Phase-II (costing Rs.18 Cr.) have been sanctioned and are under progress.
