Hi, 

I'm looking to add sound to my N-scale layout, but not using the in-diesel or in-rolling-stock method. I want to use under-layout sound because all the in-diesel sounds I have heard are not what I want. Scale sound considerations aside, I would like to hear more bass/rumbling that those small speakers can provide.

My MRC Prodigy Express appears to have stopped working.

It was running fine this morning but, this afternoon I went downstairs to run some more trains and nothing!

Symptoms: Locomotive does not respond to any commands. The sound on sound equipped engines work (a steady idle) but none functions (lights, bell, horn) respond to commands. The control unit lights up and appears to be working.

Troubleshooting efforts:

1. Tried different engines, both sound equipped and non-sound. None of them work.

I had the pleasure of attending an operating session at Jason Klocke's fantastic prototype CGW layout yesterday. 

What made this op session particularly amazing (besides the use of two ProtoThrottles – shameless plug) is Jason has recently refit some of his locomotives with Scale Sound Systems speakers. www.scalesoundsystems.com

I got most my wiring done on the swing gate so when it is open there isn’t any power on the gate and 18 inch’s of dead tracks off the gate. I wasn’t thinking about how many switch’s I required to do this when I was in the planning stages. As a result I currently only turn off the power on one end of the approach to the gate. I will purchase a couple more switches in the near future and complete the wiring.
