This thing has been known and mentioned here for some years now. Despite being a third party product (made by Brave), it works perfectly with Plarail, TrackMaster 1 and even other brands of trains. I recall wondering if it also worked with the Chuggington Motorised (not Plarail) range since I have three of them and they use C batteries.
Ucwepn (our founder) made a review of it and showed it being used on some C battery engines (and later used it in several reviews of compatible trains).
It's "Really Useful" for things like filming or public layouts, or for trains that don't have RC versions (which are easier to control but not quite as good). Also, since it uses radio control instead of infrared, the receivers can be hidden in the trains without deformation or glaring red parts. It also makes outdoor control more feasible.
