Well its an idea I have got.........Kerala that arrives TVC around 2:30pm is almost resting for 2 days....so take an example....New Delhi-Trivandrum Kerala Exp arrives TVC @ 2:30PM.....then after maintanence the next day the same rake can be used for a new TVC-CBE Day Express which starts from TVC at the morning and comes back to TVC in the evening.......then next day that rake can go as Kerala Express and this cycle can be continued and we can get a new TVC-CBE Daily Day Express..........
