I love this stuff. Seems like a massive untapped market if you get in partnership with a manufacturer. There are enough train buffs around the world, although I guess the tricky bit is that the dashboards are all different.

I found it surprising that despite having amazing international supply chains, it can still be hard to source electro-mechanical parts. I wondered about knocking up an NX signalling panel as a nice to have to my layout but sourcing those latching push/pull buttons is equally difficult although maybe they were only really used on the real thing and the demand has disappeared along with the supply.
