I wonder what would happen if all four castles were put together
Maybe I should make a topic for this.
Motorizing the new version is quite easy (as long as you have the passenger train).
You put the Receiver in the back of the engine, then you put the motorized bogie where the basic one is supposed to go. Then, the hardest part is to remove the tender of the secret compartment, so you have a 4x8 space. Then put the battery box in the tender.
Now wire it all up, and your ready to go!
