Actually Cnb to Ndls me top priority milne ke kai reasons hai.
1. Trains coming from Ald side are getting late nowadays and creating empty slots which are easily utilised by it.
2. Lesser traffic in night around midnight due to late running of many trains from Ald side
3. Lesser freights.
Reasons...
more... for delay of other SKs
1. Congestion in Mgs-Ald-Cnb.
2. Their slots are near to Rajdhani and many others get overtaken by Rajdhani and disturb others slot.
3. Works under progress in Ald-Cnb so blocks are also there.
