I think max of 30 min will be removed if speeded up....because to decrease 1h 15 min...it will require priority like TVC MAS Mail,Kovai SF...from SRR-ED we have MAQ-MS exp in front which is a super crawler....and we also have raptisagar clash bet GDR and TEL if speeded up....This schedule would suffice....it is fast enough...All i want is return 17230 should be speeded up with same timings as 17229.....17230 is the king of slack.....even if it gets overtaken by both Raptisagar series and YPR-HWH SF bet TEL and GDR...it would still reach on time at all stations starting from GDR...
