@feet posted:I like you're roller stand. Did you build it ?
Yes, designed it so could test anything I own including AA units Centipede.
In the first pic the S1 is sitting on a length of RealTrax that includes an operating section. That why can rolling stock couplers and any operating cars. Also as pictured can set the engine(s) there and then space the rollers and support track sections where would need them. Then built the shorter (18-inch) test stand to make it easier to test single unit diesels and short steam engines. All in all think have 12 rollers.
