I'm the engineer and my nephew is riding the car.
It was a bit of a tight squeeze and balancing act for an adult to run the loco. That's one of the reasons I rebuilt it. Riding the tender of the rebuilt loco was a lot more comfortable and safer.
It's sad to say the line is now abandoned. The loco and car are here in AZ. The track was left there as it will cost less to buy new track than to take up the old rail and ship it here.
A new line is in the planning stage at my brothers new house in Humboldt AZ., (3.5 acres) (about 5 miles from here).
