Thanks, Christopher, bringing up this question. There are several disused railway tracks in Germany where these cars are used for fun rides. Most of them are driven by pedals but a few are powered by solar energy. Have a look at  https://draisinentour.de/ or  https://www.solardraisine-ueberwaldbahn.de/technik-strecke/

From a formal perspective it is a normal track so my expectation would be railway=tourism and draisine=yes.

Best, Eckhard

For those wondering, like me ....  "draisine"= handcars, track cars,
putt-putts,etc (to use American language).  Little maintenance vehicles
(most often but not necessarily 4 wheels). In the past strictly for
railway service, though lately  passengers and private users have  been
using them.
