I predict that this express might have this timing from PDY..
Station / Arrival / Departure
PDY / - / 14.45
VM / 15.10 / 15.20 incl LR
VRI / 16.00...
more... / 16.02
ALU / 16.30 / 16.32
SRGM / 17.15 / 17.18
TPJ / 17.40 / 18.00
After then it might follow the same timings towards MAQ with additional halts at Kulithalai / Coimbatore Main Jn / Mahe..
