Dude there is lot of diff between RSA of GT,TN and MAS-ALP/MAS-TVC and MYS-MV and MYS TN
IF RSA is kept for GT and TN to maintain every day only one rake either GT or TN then
for suppose if GT starts on Sunday and reach NDLS on Tuesday and same rake returns back to MAS again on Wednesday mrng that means after 80hrs and if the same rake has to go as TN then the same rake which arrives as GT exp to MAS will leave as TN exp on Wednesday...
more... and reaches NLDS on Friday and return as TN exp and reach MAS on Sunday.
So then after 1 week it goes to BBQ yard........
And GT,TN willl undergo maintenace at NDLS either it is primary or secondary......that much imp these trains has.....
And during fog time GT and AP exp will get highly reschedule due to Less TAT than TN and Dakshin exp.
I am not against of keeping RSA but i wang to know what benfit does MAS dvi get.
