A guide to installing DCC sound in the Bachmann large scale/G scale Thomas the Tank Engine.

One of the easier DCC conversions I've done because there's so much space inside Thomas. I used a Soundtraxx Econami Eco-200 steam sound decoder and a 8 ohm 2W speaker from www.roads-and-rails.co.uk. Given the amount of space in the model I think I could have gone with a bigger speaker.

I found that Thomas with Annie and Clarabel derailed a lot over LGB points or when going through 1st radius S curves, so I've also got a couple of tips that will help improve running.
