People should have their own awareness to use the dustbins. I used to keep all my bus tickets after my travelling is over into my pant's back pocket and when I am alighting finally for house, I drop all the tickets into the dustbin kept on the way to my house.
Its a common feeling of inappropriate expressions on our end by the time we have stepped onto the railway station & this continues till we reaches to the other end. And within these time span we try to ignore the dirt around us as we don't find any other alternative. We are just constrained to use the toilet outside. Although each one of us can't be blamed but still the irresponsible behavior can easily be seen as keeping to ourselves so as not to irritate the co-passengers.
But at least we can do the things we find would make feel good for others. Although we already in the job but do it with more intensity because this is still your country.
With regards to the coaches kept clean, this is one of the few situations where in I see many people give money to the poor people who clean the floor of the coach and then ask for money. I also give them because at least instead of demanding like other beggars, these poor people at least do some work and keep the area clean.
Between 7PM and 10PM, there is always some unauthorized cleaning, in terms of some poor person, who would offer to clean the coaches for whatever he can earn from the passengers. Under very close supervision, in a running train, it is fine if we encourage these poor guys, as most do a very good job for the five rupees we tend to give them. Of course, there are crooks among them, who walk away with our belongings.
In long distance trains, the Railways have introduced mobile cleaning, and uniformed personnel, approach each passenger to pass on the waste stuff, for them to clean away. In the AC coaches, the attendant is supposed to clean such stuff, or arrange for such cleaning. In some day trains, like the Pamani Express that runs between Tirupathi and Mannargudi, I was surprised to find the Railway authorized personnel, cleaning the train, so often.
We, as passengers need to cooperate with the Railways. If there is a huge amount of waste material uncleaned in long distance trains, am told, the passengers can even stop the train and demand that the Station Master organize the cleaning. This is a good thing. Let us also know our rights, in this regard.
