Disneyland Railroad Cab Ride on the E.P. Ripley 

DRR #3 is named Fred Gurley, and can't accommodate cab rides. Roger E Broggie is the Walt Disney World Railroad's #3, but they don't do cab rides there. The only Disney locomotives that give cab rides are Disneyland RR 1, 2, and 4.

@@MatecaCorp My experience wasn't something arranged or even part of normal operations. On the day I was there, the engine was stopped for water, and they had cast members come out to entertain the kids waiting at the station until they were ready to go. I, however, was much more interested in the engine than the characters, so I instead asked my parents to take me to talk to the engineer. He was absolutely delighted because no one ever came to talk to him, especially not a kid when the characters were out. It was because of that he offered to let me ride along on the footplate. I will also note this was over 30 years ago, so there's a big difference in how protocols were handled. I'm sure due to security concerns, that probably couldn't be repeated today.

Go to the main street station and ask them for a cab ride. You may have to wait for up to 2 hours as some trains don’t have seats on the tender. If the EP Ripley is running you will have a good chance.

You just apply for ride operations at Main Street and basically ask to train on it as a fireman, from what I understand.
