Are bathroom available one the trains?

Technically, it right next to the museum 'bout a one minute walk away

Unfortunately not. You'd have to use the ones near the museum and thats's a short hike (about 2 short blocks?)

There is a bathroom on the Mystery Dinner train, but not on the shorter train rides.

No bathrooms on the trains. Across the street at the museum, there are portables.

No bathrooms on trains but they do have them across the street where you would load and unload from the train
