百萬城's don't know, but i was told Tomix have some item (1423) have this function.
So today,
i hv just bought a Tomix-1423 kid(very cheap), but i don't know how to work.
i hv some questions :
-if i just want to make a track line with auto backward fuction (自動往返), should i hv to buy 2-sets of Tomix-1423 ?
-from the menu(i don't know japanese), i saw something just like a electoric break at the middle of the track line, isn't it ?
-anything i missed?
