As far as frequency & stoppages are concerned, there are two daily SF Express trains linking TVC to MAS via KTYM, ERN, PGT(Nos. 12695/96 & 12623/24). Further you've the bi weekly TVC - KRBA Express (16327/28) & TVC - GHY SF Expresses(12507/08 & 12515/16) as well.
Beyond ERS, you have the daily ALLP - MAS Express(16041/42) and ALLP - DHN/TATA(13351/52), in addition to quite a few weekly/bi weekly/tri weekly services(like TVM - SHM, TVC - GKP Rapti Sagar Exp, ERS - BJU Rapti Sagar Express, TVC - INDB Ahilya nagari etc). When you've this many options, why insist that a weekly SF train, which departs TVC @ 2005 on Saturdays too should stop at all intermediate stations like VAK, KYJ, MVLK,...
more... TRVL, CGY, AWY etc?
As far as I know, 12697/98 is fetching decent loads and helps many last minute passengers get confirmed reservation. Moreover, Railways ensure hat this train halts @ TRVL during Sabarimala Season.
In this context, why be adament on stopping this train at almost every station between KTYM & QLN?
