Great work man!...sounds like a keeper!....as far as your missing cat walks, PSC ........( Precision Scale Company) sells tread in sheets in various designs and thicknesses,....easy to make missing cat walks with a descent set of shop sheers, and a handy dandy belt sander,...( quick for trimming) ....or lay a piece of sand paper on a flat surface and file away,.....MTH used a glue that didn’t stand up to the test of time on the cat walks, and other trinkets adorned on the model,....be forewarned, build plates, and all the other catwalks are held on with that same glue,....when one piece falls off, attack the entire locomotive on your terms, to save yourself the grief of missing small items ,.....a lot of times if you sneeze near the build plates, they’ll fall off,.....
