Backdating Bachmann's Thomas the Tank Engine

Sorry for the late reply. I'm not extending it, I'm just changing it to allow for the cab to go all the way down to the floor, and doing a thinner bufferbeam at the back, because the one Bachmann did is thick, even for the Model Series. Yeah, it is going to be a hybrid of those 3 things, plus some details of a real E2 will also be incorporated. I'm hoping I can make it look good. I was also planning on building a new chassis anyway, so I could put bearings on the axles (to help the model run smoother). I'm planning on designing the chassis to help keep the new running board stable, but I am going to try to make it be sturdy itself. And yeah, I did rename the thread.
