One problem with the MTH Docksider is that it never was available with DCS. AFter much study, I concluded that the PS3 unit that is in the 44-tonner would fit into it. I often discussed with a now-departed MTH person that they ought to make one. I was on the verge of converting mine, but the cost of buying a 44T just to obtain the Board and other parts (such as lights) parts turned me off. The fact that its lack of traction tires rendered it incapable to hailing many cars also turned me away.
Seem my previous videos, pulling power really isn't a problem with the MTH 0-4-0, it's a heavy little brute and has no problem hauling a bunch of cars. I'd love to have a full-feature one with sound, and I may yet put a small smoke unit in it and see if I could cram sound in as well.
