दौड़ती है हिमालय तट से सागर, हमसफ़र हर राह पर, हवाई जहाज़ों को त्याग कर, करो अक्सर, भारतीय रेल में सफर. - Arpit P

But HWH CSMT Mail via PCOI is too slow with lots of halts. I would suggest 12101/02 even if delayed by 3 to 4 hours will still be faster than via PCOI also less halts.

Yes wo via PCOI time lagega but train kafi had tak punctual hoti hai. Via Nagpur time kam lagega and distance bhi kam hai but idhar ab Punctuality ka koi bharosa nahi hai. SECR aur SER milkar trains ko delay karwa dete hain. Samarsata aur Jnaneswari bhi theek hi rahenge. But if you ask my choice via Nagpur, it would be either Duronto or Gitanjali

Take 12101/12102 Jnaneshwari SF, fewer stops than Gitanjali. Cons of Gitanjali is midnight arrival at CSMT. Jnaneshwari will reach LTT early morning (so usual 2-3 hours delay may not be that big problem)

Out of all these 12101/02.
