I know this is coming late, but we have autistic people and wheelchairs all the time! The volunteers and staff would be more than happy to have you aboard!
I have to agree with others call first. They have different sections of the train and we did not walk through the whole train just boarded the section where our seats were. Please call I will pray for you that they can accommodate you
I don't remember seeing any kind of wheelchair ramp. But I would call they may have an alternate way to board the train.
I'd give them a call and ask.
I dont think they can accommodate your wheelchair onto the train
