Train 18 - तेरी प्यारी प्यारी Livery को किसी की नज़र न लगे

Not essentially Pit Lines, they're more of Stabling lines.
3 of them are there.
One is used to park Bilaspur- Rewa Passenger/Express
The other one is used to park Rewanchal Express for the day
And...
more...

the third normally has Parcel Coaches, or other not frequently used Coaches- sometimes it was also used to park Chirmiri Passenger.
There's also a bypass line behind but I've never ventured there, so don't know the exact purpose for which it's used.
Though I haven't visited Rewa Station for past 5 months (as I used Allahabad route directly this time), so I'm not that up to date with recent developments in last 5 months.
