GB gondola hopper HO, N, S, TT, O scale

This is an HO scale model of a GB PRR (Pennsylvania Railroad) gondola hopper as drawn using plans found here https://goo.gl/jn84hJ. This also mirrors a model I am after, and Illinois Traction System (ITS) gondola, later called the Illinois Terminal Railroad (ITRR). This model is designed to accept Tahoe Model Works arch bar trucks, and Kadee coupler boxes. This has everything but the brake detail, that will need to be added separately, as well as the trucks and couplers.
