Tangent Scale Models G31B

The G31 series were the first post-war gondolas, introduced in November 1948. The class featured a 52'-6" interior length and a fishbelly design. These cars lasted well past the Penn Central merger. Sub-classes ran from A through N and included multiple builders and spotting features.
