I have travelled by Eastern Railway, Southern Railway, South Eastern Railway but the best travelling experience was from Mumbai to Pune by Shatabdi Express.I was amazed by the speed of the train which reached you to Pune just in about 3 hrs.The services given by the staff starting from distributing the Moring newspaper, the coffee, the sancks not to forget the Bisleri waterbottles is worth aprreciating. The lovely channel music enchants you with good classical music and old Hindi Melodies.The toilets were well maintained and was very clean. I wish they should run many more Shatabdi connecting all places of interests.
