All trains have bathrooms; the question is are they working and are they clean. The larger faster trains generally have a lot of bathrooms and they are usually clean.
Local trains have bathrooms, but not in every car and they may or may not be clean or working. When you travel by train in Italy bring hand sanitizer and some Kleenex, because most will not have soap, water and a hand dryer!
