The 2328 Burlington GP7 was one of three road names to appear on this all new diesel style of 1955. The other two GP7's introduced in 1955 were the 2028 Pennsylvania and 2338 Milwaukee Road . All three GP7's have become desirable and collectable diesels. A common problem with the 2328 is the quality of the silver paint. Frequently, the silver has tarnished or become 'washed out' in appearance. Locating a Burlington diesel with a high quality silver exterior will require some effort.
