Sir,
For ur information, i havnt find clean & hygenic train throughout India!!
Cleanliness depends on:
1. Journey: Overnight Trains are always cleaner & most Guj/ADI trains are overnight, while any train running from UP/Bihar towards Guj/ADI is having long run. But still, u have Tapti-Ganga very much cleaner
2....
more... Cleaning Facility Enroute: LKO/CNB rarely offer enroute cleaning facility, while JHS does. But JHS is much more involved in Main-Line trains, rather than bye-passing train towards ADI/GKP
3. Track Condition: Sigle & Cnjested route in between JHS-CNB makes train late & so cleanliness enroute get affects (as staff has to be pre-planned according to train schedule)
4. Train Type: SPL Trains always has bad record in terms of run/cleanliness!! Only overnight SPL Trains are having higher chance of cleanliness!!!
5. Gentry: Here i do believe that gentry too define trains' cleanliness, which is true PAN India!!!
6. Train Count: Less train against demand, are always crowdy, making it tough to maintain cleanliness!!
PS: LKO MAIL, PRAYAGRAJ EXPRESS, SHIVGANGA, RIVA, KAIFIYAT, SAMPOORNA KRANTI, SWANTRATA SAINANI, TAPTI-GANGA, LKO/ALD DRNTO, VAISHALI, SAPT KRANTI, MUSSURIE EXP, PUSHPAK, UDYOG NAGRI, MARUDHAR, ,,, ,,, ,..............
The list goes on, in which many trains are class apart
