Brake Rigging

USRA Mikado Brake Rigging

Based on USRA drawings for the component parts (i.e., beams, links, equalizers & rods), but I had to figure out how the pieces fit together for the whole rigging.  Let me know if you see anything incorrect.

Builder's Plate

Engine#32 Builder's Plate

"Replica" builder's plate for engine # 32. The font is close but not accurate to that used by ALCO for its builder's plates. Questions: Is this blue close to the background colour use by ALCO and was the colour any different for the Rutland? ALCO seemed to have changed its plates around 1918-1920 with the earlier ones not having a raised boss under the attachment bolt.?
