Hyderabad Metro Rail has planned three maintenance facilities (train depots) for stabling and maintenance of trains, rail systems and engineering maintenance vehicles.

Each line has a supporting depot where all the trains of that line shall be stabled in night. These maintenance depots are manned round the clock and are equipped with all facilities and resources required for efficient and effective maintenance of rail system assets.

The three depots planned in 72 km rail network of Hyderabad Metro Rail are located at:

  • Miyapur for Corridor 1 (Miyapur –LB Nagar)
  • Falaknuma for Corridor 2 (JBS – Falaknuma)
  • Uppal for Corridor 3 (Shilparamam – Nagole)

The Uppal depot is the main depot cum workshop where the overhaul and corrective maintenance facilities for whole fleet are planned. The other two depots have basic facilities for scheduled preventive maintenance and minor corrective maintenance.

Major facilities planned in these depots are:

  • Automatic train wash plant
  • Inspection and workshop bays
  • Offices
  • Depot control center
  • Covered & open Stabling lines
  • Infrastructure maintenance facilities
  • Electrical & Mechanical workshops
  • Electronic repair shops
  • Open and outdoor storage facilities
  • Wheel profiling lathe
  • M&P for repair & overhaul
  • Training, conference rooms, Cafeteria etc.

The maintenance workshops are managed by a team of managers who plan, coordinate and managevarious activities in depot to ensure that the trains are well maintained and cleaned for daily passenger service.

Every night when trains return from revenue services the trains are thoroughly washed at train wash plant before it is stabled on stabling lines. Daily internal cleaning is carried out before inducting trains in service to provide clean environment and ambience to passengers.

The trains are inspected, checked and certified 'fit-for-service' to allow train service in passenger service. This requires thorough analysis of data downloaded from train, visual inspection by team of engineers & technicians, successful completion of on-board test of vital safety systems and other comfort functions of trains.
