I want to do this with my mom, wife and son. My mother and I are both handicap. I myself depend on a walker to get around. Is there handicap accessible that we can ride?

My suggestion would be to call the GSMR and get advice. I can tell you that the car I rode on wouldn't be able to accommodate you. That said, maybe they can find a way.

Yes they do provide golf carts that will take you to your train .

They have golf carts to take you to the loading area for your train car. I saw several handicapped people board the train we rode. Dont know if every car or type of service is accessible, but at least some are.

They have a lift to assist you boarding the trains

They have handicap seats but not sure how they board has steps at end of cars
