Wish SR extended 16307/8 to TVC instead of idling this full rake fit to run a new, daily Intercity Express service(ERS - SA or something similar) at CAN, just to maintain RSA amongst 16303/4/5/6/7/8.
If they shift PM of 16303/4/5/6/7/8 rakes(total 4; but can be managed with 3, if shifted) to ERM, train reaching TVC as 16303 can return as Executive Express to CAN; And Executive Express reaching TVC can go back to ERS as Vanchinad Express.
The rake operating 16305/6 gets sufficient rest for PM @ ERM(it reaches around...
more... 2030 & returns to CAN at 0650 next day).
Even before suggesting TVC will point out that ERM pitlines are full at night. Incidentally, the construction of a 3rd pitline is almost 95% complete; but hardly any 'intent' to complete it & go operational!
