Hello, this is my first post here, so I hope it's in the right section, etc.
A friend recently bought a Harry Potter Hogwarts Express G-Gauge train set without the remote. We got a Polar Express remote control from the "auction site" to use with it since the Hogwarts Express remotes are much more expensive. I'm pretty sure both are operating at 27MHz, but the engine in not responding to the remote. I can see a signal from the remote at around 27MHz on a spectrum analyzer, and when I widen the response, I can see what appear to be pulses, so I think its working properly. The engine turns on and makes sound effects, but that's it.
Is the Polar Express remote control compatible with the Hogwarts Express train?
Are schematics or wiring diagrams available for the older 27MHz Hogwarts Express?
