B&O m-15k & M-15n


Brian Carlson
 

What was the difference between the two B&O wagon top rebuilds? Based on a review of freight car diagrams, it appears the underframe was rebuilt to a straight center sill using Z sections versus the fishbelly center sill of the earlier rebuild.

Were there any other changes? Specifically to the superstructure.
