U mean, BSP-TPTY Exp will come VSKP with single SLR Coach???
U mean, 17206 will run twice a week (W/SAT), against 3 days run, as of now (M/W/SAT) & even then, it will be clubbed with BSP-MMR Slip, which run on W/Sun from BZA onwards???
Quite complex situation & the same prevail since 10 years, as per u (which seems not-possible, as only 1 day, both train's run gets clubbed in-between BZA-MMR)???
