SWR cant interfere, for example when TT is prepared SCR is given slot by CR (Dadar exp) btwn WADI(exg)--->Tiruttani (say)...its upto SCR what it does and how maintains TT. SCR gives mnay stops in GTL division for revenue of that division. So the case of four trains, the issue lies with RB and ECoR and it is immature to blame SWR. Thank You.
