Yes the train still goes if it's raining.
I think it runs when raining. Inside 90% of time.
A lot of what they have is indoors or sheltered. There will be some short (less than a city block) walks between the exhibit areas. The train runs rain or shine I believe.
If it's raining you can go in the shed and look at train cars. I think all the engines are outside? Should there be a discount on rain day?
