~using train bathrooms after days of travel are a bit like using a port-a-potty.
~it is possible to have two seats to yourself; wear headphones, spread your stuff out, don't make eye contact at train stops
~drink water...lots of it.
~if you are going long distances, for days, you will see love connections made...a variety of kinds.
~some people obviously don't mind the port-a-potty atmosphere for said love connections. Get it where you can ??
