boxcar roof mystery

Chet
Craig,
You may already have the answer as I am just now reading a few days worth of messages I jumped over. But starting with WAB 89300, the roofs were the diagonal panel type. Chet French Dixon, IL |

Dennis,
The "mixed panel" roofs were discussed some time ago:
Ed Hawkins wrote:
"Dave, I have confirmed the following cars having the combination diagonal
panel/Murphy panel roofs. There were probably more. All were auto cars with 15' wide door openings built new with these roofs. You have already referenced Tony's book and some specific SP cars. D&TS 5000-5099, 2-55, Greenville MP 88900-88999, 6-57, MP NJI&I 3300-3399, 1-51, ACF NKP 86100-86249, 12-49, ACF NKP 86200-86349, 1-55, Greenville Numerous SP cars, 1950-1956, all built by SP WAB 19800-19999, 5-53, ACF WAB 20000-20199," Guy Wilber wrote:
"Ed, Other than the SP cars, none of the above cars were equipped with Auto~Loaders. The balance were in parts service. Whether, or not, the cars were purchased by the respective roads contemplating installation of Auto~Loaders I do not know. Until Evans developed the Type "F" with a boom hoist and the Type "G" the rectangular panel was required to facilitate the supports for the lifting sheave hanger frame and the similar frame that supported the safety hook assembly used to secure the racks when stored against the roof of cars. Evidently, Evans lift assemblies were also used within auto parts cars utilized for shipping car bodies. I have some literature on the system but have yet to find a complete installation drawing. I believe that may offer another connection to the mixed panel roofs." Regards,

I seem to recall seeing some 40’ box cars that were stretched to 50’ using diagonal panels in the middle of the cars’ rectangular panels for the roof.

SP built some automobile cars with such a feature, doubtless the same reason. Tony Thompson |

I was going to mention, but Ed beat me to it, that the built dates span the production change of the roofs. Not really a big deal, as the panels (the whole component, not just the raised pressing) were interchangeable. Seems I recall the NKP had some auto cars that were built based on an earlier design, where it was found the new diagonal pressing interfered with the loaders, and so the cars were built with diagonal panels EXCEPT for two; those were the older recangular design to gibe the needed clearance.

Craig, The 50 cars reassigned AA 250-299 ca. 2-55 were the former WAB 89550-89599, built ca. 1-50 having diagonal panel roofs. These were the last 50 cars of original series WAB 89300-89599, which also came with the 1948-1954 version r+3-4 Improved Dreadnaught ends. Not part of your question but related to the original 300 cars WAB 89300-89599 were 17 cars re# in 11/50 as part of new series 9225-9299 & 8 cars re# in 11-12/50 as part of new series 9363-9436 when equipped with DF Loaders. The other 500 cars WAB 88700-89299 in the series you mentioned were from an earlier order built starting in 3-48 having 4-4 Improved Dreadnaught ends & Murphy rectangular panel roofs.

A question from "the bunker" as I dig into the pile of long put-off projects:
I'm starting to work on a model of a specific Ann Arbor RR boxcar. Fifty cars that were originally built by the Wabash RR circa 1948-1950 were transferred to the AA in 1955 becoming AA 250-299. Built as WAB 88700-89599 these were 40-foot boxcars with 6-foot doors. The question of what type of roof to use has arisen. I have a copy of the page for these cars from the Ann Arbor RR equipment book (a drawing revised Dec. 1964). It specifies "Std Ry Equipment Co (7R-12712)" for the roof. Does anybody know if this is a "diagonal panel" or "rectangular panel" roof? The Morning Sun Wabash, Nickel Plate, DT&I Color Guide has a photo of WAB 88836 that seems to show a rectangular panel roof. And while I have collected lots of photos of the AA 250-series cars, only one shows an angle where I can make a guess as to the type of roof. The AA car sure looks like it has a diagonal panel roof. Since these cars came from the WAB series that shows a rectangular panel roof, shouldn't the AA cars be the same? That is why I am hoping the Stanray designation from the equipment diagram will provide an answer. These are cars that definitely fit into the STMFC guidelines and I figure the esteemed members of this list are as good a place as any to start looking for the answer. I can recall a time when getting this right wasn't as high a priority to me as it is now . . . Craig Wilson |
