Have two friends printing quite a lot of 3Ded steamers and diesels. This one for the S2 has quite a lot more and has an Ebay store. Engine chassis used is the Spectrum Class J as its the only one with side rods closest to what the S2 used. Tender chassis used is a Bachmann long haul chassis shrortened as well as center section of weight cut out for splice plate as well as being able to reverse one set of trucks for both side electrical pickup and adding the Class J's tender electronics. Bachmann metal drawbar was also used. Did do quite a lot of changing on the origional 3D prints for a more prototype appearence. Made my own forward and reverse turbines, added highly detailed pumps, built and added the generator and other detail parts, etc. 3ded door ladders removed and brass ladders added. All side hand rails, door rails, duel turbine throttle linkages, both side plumbing and others made from brass and bronze wire. Also built his Pennsy S1 using a highly converted BLI T1 which I will also post, I used the same Pennsy decals on the tender for the S2. Also both six axle end trucks on both the S2 and S1 were 3D printed. Smoke deflectors are removable in order to run before they were added.
