Volume 9 of Railroad Prototype Cyclopedia has a very nice article on

the wagon top boxcar and explains all the differences.

Can anyone help with identifying the differences between the

designs of these cars? I'm in the process of correcting a botched
modeling job on a pair of West Shore models of the M-53. The way that
these cars were put together indicates that the guy didn't know about
Duryea underframes, but by undoing much of what he had done I was able
to make one of them into a passable M-53. I'd like to make the other
into an M-15 with Youngstown doors, but lack info on the differences
between them and their later clones. Any help would be appreciated.
Thanks, Tony Wagner

Tony,

The B&O Historical Society still has the RP Cyc in stock.

When building the M-15 wagon-tops you have to decide the period you are
modeling. All the M-15 wagon-tops received new underframes starting in
1955 except as noted in the article the 50 double-door automobile cars
in class M-15L. This was a very rapid process that was completed in
about one year so there is very little overlap of M-15 wagon-tops with
the fish-belly underframes and the AAR underframes.
