this trains are good example of good relations between SR and CR. Like transfer from SR to CR. Despite the slow route and lots of slack all three trains are ideal in their own ways. My favourite is the slowest MAS mail, which makes me reach MAS at 3:30 am, so much slack ensures she reaches before time always and from there I can catch morning's Raj/GR/Drnt/DD which all depart after 6 am.
After electrification and doubling of route, I am sure, Mas Mail wil also become SF mail like MAS-HWH Mail or CSTM-HWH Mail via NGP and CST-MAS Exp would also become a SF like MAS-HWH Coromandal or CST-HWH Gitanjali.
