• Trains run only on set running days, like the lantern day on Nov 1 and Nikolaus day on Dec 6; on the public visiting days in between, the halls are open but nothing moves
• One ticket, unlimited rides on the trains all day, sold only at the entrance desk with no booking needed
• No parking by the museum, since the street spaces on Am Römerhof are closed: come by bus 50 or 89, or park at Rebstockpark and ride the train in on running days

The Frankfurter Feldbahnmuseum keeps about 75 narrow-gauge field railway locomotives and more than 200 wagons in three halls, from hand-pushed brickworks carts to the world's smallest articulated steam locomotive, built in 1909 for sugar cane lines on Java.

On running days, steam and diesel trains carry visitors along a 2 km line through Rebstockpark. The volunteer club restores its own engines, with teenagers working on some of them.
