Bathroom facilities on public transportation

All trains have facilities generally about every other or third car.

But the facilities are... well, let's just say they lack charm.

we took a train from london to bath and back. the train toilets were fine, even on a late night friday train back to london (that was packed with drunk people[INVALID]not sure why) the facilities were not any worse than, say, a public fast food restroom, which, as someone who needs facilities more often than most, i use all the time. you'll be fine[INVALID]have a great trip! oh[INVALID]and some tube stations do have restroom facilities[INVALID]embankment station has pay toilets outside the south door. were they expensive? yes. were they clean and available and very much appreciated?[INVALID]absolutely. OH[INVALID]yet another tip[INVALID]train station facilities often close at night and in the early morning (from, say 11pm or midnight until 6 or 7am), so if you are getting OFF of a train late at night or early in the morning, use the on board toilets before you get off. again[INVALID]have a great trip!

All trains are designed to have toilets. Older trains have porcelain toilets which flush directly onto the track below so you must not use them in stations, the newer ones have stainless steel like the ones on aircraft and use a vacuum process and storage tanks. A problem with the newer toilets is they have much more complicated mechanisms so sometimes they lock themselves out of use. If you are stymied by this there may well be another toilet elsewhere on the train. ... Also, modern trains will have two types of toilet compartment, a normal one and a "disabled toilet" which is a large, usually round, room with plenty of room and features to help wheelchair passengers. It is usually next to the disabled area, which is indicated on the outside of the train with a wheelchair or pram icon on a blue background. Anybody can use it. Don't push any red buttons which are emergency call buttons. They stop the train and put you in communication with driver and the guard will come and let you out and lecture you. .... On trains with football crowds on the guard may lock the toilet to prevent vandalism. If you need it, seek them out. They are usually based at the back of the train. Knock on the door and they will come out. ....... On board toilets should be equipped with washing water, soap, and a hot air dryer (no paper towels). These may be concealed so look for hints. ... Many London Underground stations have toilets, TfL have an online guide. Many but not all national railway stations also have toilets, Marylebone being some of the best, and free. Go to the National Rail Enquiries website and click on stations and enter yours and it will say. .... Don't be afraid to ask, locals have to pee too.

Thank you, everyone, for your replies! Did I understand correctly that there are bathrooms on board the Tube? While in London last year, I never saw them; in the tube stations, yes, but not the cars themselves.

Cindy, to the best of my knowledge and memory, trains on the Tube do not have bathroom facilities.

No bathrooms on Tube cars,, but on regular go out of London train yes..

and what I meant was in various Underground stations, not the cars themselves.

And usually only in larger Tube stations, ones with rail links... there are a few non-rail ones that do, but not very many. And always have small change ready, as they're usually pay to loo!
