New engine, that's being fixed, is my 1st engine with sound. I too come from building and running HO / N layouts.
It's nice to be able to control sound output from a controller. Once I idled it into bdrm, then full volume along with horn. It will wake you from a dead sleep. Well the wife quickly sat up...
So, anyone ever think about doing this? N scale track fits nicely between one side of rails. Run 2 different sizes of trains. Wonder how many cars the mini SD70 would pull... Just for laughs.
Poll wouldn't see it up on the shelf.
