Study Notes

  • Rail transportation systems require railway tracks, signalling, telecommunications, rolling stock (locomotives, coaches, wagons), and maintenance/operating personnel.
  • Rolling stock and crew needs depend on traffic volume; planning is crucial for efficient coach acquisition and use.
  • Rake links optimize coach utilization, minimizing downtime at destinations and ensuring timely inspections for reliable service.
  • Rake links detail the coach movement sequence, providing a quick reference for operating staff.
  • Rake links aim to maximize coach running hours and minimize terminal station delays, leading to maximum utilization and minimum lie-over times.
  • Coaches must be available for trip inspections at terminal stations, and this information should be included in rake links.
  • Coaches must be available for scheduled maintenance at their respective owning depots (monthly, quarterly, etc.).
  • Terminal stations need ample time (at least 3 hours) for connecting other link trains to minimize link failures.
  • Rake stabling sidings should be available at terminal stations close to platforms to avoid unnecessary shunting movements.
  • The Panchvati Express (1001 DN/1002 UP) has primary maintenance at MMR and secondary maintenance at BB.
