Bad light dimmed Railways' chances of a first innings lead as Himachal Pradesh moved to 125 for 2 on the third day.
In the 45 overs played on Thursday, the visitors scored just 91 runs, leaving themselves with a task of playing out 90 overs on Friday.
Despite the loss of play on Thursday, Railways will still enter the final day as favourites what with their spinners keeping things tight.
The only concern for them could be the failing light.
Things were going rather well for the hosts on the third day as they got rid of the Himachal openers.
Bhavin Thakkar was removed early by Murali Kartik while Sangram Singh, in trying to break the shackles imposed by the Railways spinners, was stumped off Karan Sharma. The leg-spinner bowled well and kept the pressure on.
He could have had Paras Dogra too, who was struggling, before bad light intervened.
Railways 419 vs Himachal Pradesh 125/2 (Sangram 50, P Dogra batting 35, M Kartik 1/25)
