I'm wondering if anyone knows what ever happens when you use the toilet in the train; and in particular, the Malaysian bound train in Singapore. The question comes to me as I often choose train rides whenever time permits and almost always will use the toilet before reaching the customs checkpoint.
A search online reveals that the trains are using a 'Hoppers Toilet' system. That explains how a person can see the railway tracks from the toilet and there's a sign urging users not to use them at the stations.
What happens is that whatever is being done in the toilet, it gets flushed onto the tracks directly.
I wonder if the folks who like to hang around the tracks, sitting on it, lying down on it and even sticking their heads through the tracks knows this?
Anyway, for more information on hopper toilet systems: http://en.wikipedia.org/wiki/Passenger_train_toilets
