Lionel 6-9113 N&W 4 bay hopper

Here is the same model with MTH roller bearing sprung trucks installed. This process required drilling out the rivet that holds the plastic trucks.

No question on the value of the change in the trucks.  MPC's decision to switch from the postwar-derived plastic AAR trucks to those completely obscure Symington-Wayne trucks starting around '71 / '72 is beyond comprehension.  Their only saving grace IMHO was the fact they were made of Delrin (engineering) plastic that combined with fast-angle wheels & needlepoint bearings made them roll very smooth compared to postwar.

That car was a remake of the postwar 6446 4-bay covered hopper although this remake came without a cover therefore the spreader bar.  It’s not an easy car to find as it came in the 1973 CP Service Station Special Set.  I don’t believe it was ever included in any other set or cataloged for separate sale.
