Mayank Agarwal continued his good form with a fine 89 off balls (15 fours) and shared a 132-run fourth-wicket partnership with Pavan Deshpande (65, 67 balls, 9X4, 1x6) as Karnataka made 257 all out in 48.1 overs.
The home team slid from 182 for 4 to be all out in 49th after the fall of Deshpande as the Railways bowlers tightened things up.
In response, Railways were in trouble straightaway as both the openers failed to open their account and the fall of a further four wickets left them tottering at 54 for 6.
Anureet and Ankit were involved in a 91-run stand for the seventh wicket to revive Railways' hopes. However, young medium-pacer M Prasidh took three wickets to hasten a collapse and the visitors were dismissed in the 48th over.
