Sir......Chill !! If you read the post etc, all the members of Kerala have said that it is a useless proposal........Not a single member has defended it. Its just that a newly elected MP (first time in parliament) who has made this demand. In any case MP's keep making weird demands and most of them do not have much understanding abt pit lines, maintenance, rake availability,slot availability etc etc.
Ultimately the end decision lies with railways.
