Nowadays Jan Shatabdi is just a name only and so is Duronto, Rajdhani etc. Everywhere mix up is going on, not a single class of trains has the proper amenities that's promised from Railways.
Recent example in Varanasi, Modiji aa rahe hai toh a train needs to be started, even Railways didn't knew that whether Patna Manduadih Train was a Jan Shatabdi, Intercity or a Mahamana. ЁЯШВЁЯШВ
Bas Mantriji aaye hai toh kuch toh chahiye.
