Well bro, it isn't new to me. Already took a ride in Kalka-Shimla NG exp. But this time uphill was a bit higher side. Tunnels here are very much lesser than Himachal but those small mountain rivers & steams are in huge number here. Seating arrangement was better in klk-shm, but here 6 seaters are covered by taking the full width of the train which made the coaches very crowdy & minimum movement wasn't possible.
But still when the train started I forget all these uncanny things happening around & enjoyed the fullest.
