Thank you for your kind words. It's been a pleasure to share these models. I figured someone would fit a decoder under the chassis but I had no idea one would fit in the cab area. Wow, that's fine work! While I'm here, I'd like to apologize to anyone that was not able to get a set of 44 Tonner handrails before they sold out. My supplier sent me the next batch but shipping is extra slow these days. Happy Holidays, everyone.
