About this video
We're revved up with a new TrainMasters TV exclusive series! Trevor Marshall hosts, with techniques for super-detailing, painting and weathering locomotives and rolling stock from award-winning modelers from across North America. In our first segment, Efram Ellenbogen upgrades an Athearn "Blue Box" SD40-2 with a Overland brass chassis. There's more to it than just swapping out the old mechanism, and he has some great tips for making the transition go smoothly.
