U won't believe brother, trains to and fro MGR Chennai Central thankfully have the TBs as MGR Chennai Central, but in the announcements you should hear this.... OMG... they LITERALLY mention the full name as per the TB... that really pisses me off.... they can very well mention it as, for eg. Alappuzha MGR Chennai Central SF Express instead of Alappuzha PTMGRC SF express.... OOF....😑😑😑
