Would like to share my recent experience with the Green Line from Pindi to Karachi... let's go by bullet points as shared by bhai @xoofi or being asked by many readers,
1) Timing is sharply matched with the given schedule on website, it left Pindi on dot 3:40 . All the way we kept checking both and to our surprise , actual timing and schedule matched just with a difference of 2/4 minutes.
2) Even though passenger's wish was not taken but the dinner and breakfast was very tasty, fresh and more then enough for one passenger ( 2 naan + Chicken Qaurma + Chanay ki Daal + Raaita +Tea in Dinner & 3 bread slices with omelet + Tiny packets of Jam and Margin + Tea ) . Moreover we were served one sandwich just after an hour of Pindi Departure.
3) Wifi does work fine on main stations or with in City, you will loose wifi when it crosses deserts and villages within the route.
4) Water bottle was on dispenser and moreover there were 2/3 filled bottles kept there to replace immediately as one gets empty
5) Liquid soap and Toilet papers were always available in washrooms
6) Cleaning staff comes 3 times in your coupe to take out all the trash and clean the floor
7) Extra tea is available anytime you need in just 20 rs
8) 4 channels were on-air to the LCD and it repeats 2/3 same movies to the whole journey so its better to take your usb.
9) AC is as chilled as we had to request to make its coldness low, there should be a separate switch to every coupe to manage temperature on their own.
10) The corridor is little compressed as only one person can cross it easily and if two comes in front then they will have to bend. It has folding chair also there if someone wants to enjoy the sightseeing but space issue is there.
11) One Newspaper served in one Coupe.
12) Pillow and other arrangements were quite clean
13) Background music is also there through out the journey , you can manage its sound by a switch in coupe.
14) Attendants and other staff are friendly and active.
15) There is a separate small light bulb on each berth for reading or any use at time of night or darkness without disturbing the whole coupe.
These are the observations which i could conclude right now , will add anything more if comes in my mind . It includes all the positives and negatives of Green Line i observed but i still believe it is a great addition for those who can afford little expensive tickets just to enjoy the train journey with comfort .
