mannai exp....the perfect ONT trains on both sides.....nd speed looks nice....with nice no. of stops
as uzhavan exp is concenred it is having odd time arr at tbm nd ms as well...nd late nit departure on ms
boatmail.....now cannot b considered as a nice train to tj as uptrain reaches tj untime (2 am) nd ms bound train also reach tj late nit....but it acts like a nice ONT b/w tpj nd ms....also it is a decent train to rmm after sethu...(other option :P)
mahal......a...
more...

gud SF train.....if increased to daily nd giving preference to crossings nd slightly speeded up it can act as a best ONT train to tj nd tpj as well.....(though ms bound train arrives untime at tj)
TCN exp.....as per me its a gud train but not so punctual...it ariives tj almost an half hour late(tcn bound)
so fr tcn,boat mail nd mahal very much slack is given b/w tj nd tpj atleast 45 mins is enough to travel b/w tj md tpj non stop.....lets see the effect on these trains after tj goc doubling......
