If you have to catch any train from mumbai (you living in Pune) whose departure is at about 11 am to 1 pm , and don't wish to hamper you one night's sleep , then take this train. Fare is lower as compared to other trains but positive thing is you will get a full fledged 5-6 hrs night sleep. You can even opt for 3A class , but i will suggest you SL because overnight journey in SL is very safe with RPF escort patrolling and a fully attentive TC who is dedicated for just 3 coaches. Negative point of this train is now a days it always arrives after midnight at pune. It trail the CSTM Mail, Shatabdi and Konark all the way from SUR (Priority worsen only from last year; earlier it was very punctual train but condition got poor from last year).
Still...
more... if you have ample amount of time as buffer at mumbai , then go for this train.
