Modifying the Lionel 6-9135 N&W 4 bay covered hopper
This model is a very basic O-27 4 bay hopper that was issued in 1970. (BLT 9-70) It was produced by Lionel Toy Division of MPC, Mount Clemens, Michigan. The model has plastic trucks.
Custom end of car brake gear, formed metal steps and sprung trucks were added to upgrade the model. The truck centers were adjusted so that the trucks are positioned closer together. Although this model is O-27 size it operates on standard O-27 or O-31 track suitable for smaller layouts.
