Most of the specials in this region are being run taking in to account just rake availability & not passenger demand. Lone exception will be 82632 ERS MAS Suvidha which leaves ERS on Sundays @ 1900(82631 leaves MAS @ 2230 on Fridays).
You'll have enough passengers if a similar special is run between SBC & ERS; but the present special is leaving on Tuesday @ 1700.
There's another ERS - POY - RMM special which leaves on Sundays & crosses the legendary Pamban bridge at wee hours(RMM arrival 0400)!
However,...
more... as it is vacation time, even oddly timed special trains are finding many takers.
Only KCVL - PDY & KCVL - KIK special trains seems to have got cancelled due to poor patronage from Kerala.
