जिंदगी में शादी के अलावा ट्रेन में RAC ही एक ऐसी स्थिति है,जिसमें दो अजनबी साथ निभाने को मजबूर होते है। - Junaid

Pit Line are washing lines with open dumping pit at base, throughout the track.
- These pit are utilized to drain out sewage water (Washroom & Coach Interior Cleaning).
- Thorough Checking & Repairing Coach Base parts
- Newer Pit Line are equipped with water pressure cleaning facility, to wipe out exterior of coaches!!

#Is no of Pit Line dirctly proportional to no. of train originating??
Yeah, it does!!
But that depends on many factors like,
1. Pit Line Capacity & Efficiency- Single Pit Line with 24 Coach Handling Capacity can easily manage more trains, when compared with Pit Line of 10-15 Coach Capacity
eg. LKO Pit Line manages LKO Mail & Gomti Exp (24 Rake) at one shot, while SLN manages Sadbhawna (18-22 Rake) in two shifts
2. Primary vs Secondary Maintenance Depot - If the Station act as secondary Maintenance Depot for most originating trains, Low Count of Pit Line can manage increased numbers.
eg. NDLS/NZM is secondary maintenance point for most DRNTO & so no extra Pit Line required for DRNTO.
3. Train Run - Station having Intercity trains as originating/terminating point can manage with lesser Pit Line, while opposite for long running train's station.
eg. LKO vs LJN - LKO do have intercity as originating/terminating point & so is managing with existing Pit Line, while LJN got many long run trains recently & so got 5 Pit Line recently!!
4. Train Timing - If trains' departing time are close (withle difference between Arrival and Departure), with increasing no, then saturation point may achieved faster (with limited no of Pit Line). Then either
- Newer Pit Line need to be installed or
- Switching of train to nearby station or
- Weekly Train will remain Weekly or
- Non-introduction of train or
- Non-managed & unclean rake would become practice
etc etc
