It is not radio but infrared but that could be OK. I will be careful when I disassemble it so we can use it for a Christmas present if it does not work out. You need a special triangle screwdriver to open it, so good old Amazon came through. It has a powerful motor and radio system, and the quality is very high. I will check it out to see if it can be used in a model train.
