Tinsukia is highly underrated. It provides almost 1.5 times the number of passengers than what DBRG provides. Open any train chart and you will find the data. For example, this is the data of Avadh Assam that departed today from DBRG.
1A DBRG 2
1A NTSK 6 (3 times)
2A DBRG 12
2A...
more... NTSK 40 (3 times)
3A DBRG 70
3A NTSK 100 (almost 1.5 times)
SL DBRG 103
SL NTSK 155 (almost 1.5 times)
Total DBRG 187
Total NTSK 301 i.e. 1.61 times.
Guess railways should construct more pit lines at Tinsukia so that NTSK - DBRG -BOGIBEEL and NTSK - DBRG - MRHT - MXN could be properly utilised.
