- 2. • TheAlambagh workshop, near Lucknow, was set up in 1865 by the Oudh and Rohilkhand Raiilway. It started off doing minor maintenance and periodic overhaul of coaches and wagons, and eventually became one of the top workshops engaged in overhaul, repair, and restoration of carriages and wagons. Today the workshop specializes in the new high-speed coaches (LHB Alstom, IR20/IRY, etc.), airconditioned coaching stock, etc. The Basic Data for workshop are as under • WORKSHOPAREA = 204684 Sq. Mtrs. • COVERED AREA = 72595 Sq. Mtrs. • POWER CONSUMPTION = 14666 KWH/day • WATER CONSUMPTION = 1575000 Ltrs./day
