Port-a-potties require frequent emptying and other kinds of maintenance. Other kinds of dry toilets are under development which would address this issue in a variety of ways (e.g. composting toilets) and be applicable to all sorts of interesting scenarios (e.g. remote places in the developing world, where proper disposal of human excreta is a severe public health concern) but overall they're not yet ready for prime time.

The elevator at the train station also requires frequent power washing because people pee in it. The maintenance of the porta pottie is already being paid by society especially by our metro in added custodial needs. Why not just implement it then? Contain the piss and poop?

Shouldn't a train station have restrooms somewhere already?
