Still Other Prototypes for the Atlas/ Lifelike X-29? Now for some of the other roadnames in which these N models came decorated... I have a Santa Fe car, and I have a fairly comprehensive library of Santa Fe information. I can confidently say Santa Fe didn’t have these. Someday, I may want to strip my model and reletter it for something else, maybe NYC. I have a car that came painted for NYC Pacemaker Service, and we know NYC had cars like this, so it seems likely the model is close to something. However, the Pacemaker cars pretty much stayed on online dedicated service, so I don’t need on my Santa Fe layout. For railroads other than Santa Fe and NYC, it’s harder to count them out. I don’t have information for every car owned by every railroad in every time period. However, I do have an April 1954 Official Railway Equipment Register which gives dimensions and AAR Mechanical Designation for nearly every car in interchange service on that date. The X-29s had an internal length of 40’6” , internal height of 8’7” and classification XM with description “all steel.” I have “Made in Yugoslavia” X-29s lettered for Western Pacific and Nickel Plate. Neither of these had boxcars of these dimensions in 1954. Cars listed in Irwin’s Journal Atlas A1g site: #2381 Penn Central #65638 #2382 Canadian National #523975 #2383 New Haven #36409 #2384 New York Central #174478 “Pacemaker” #2385 New Haven #40045 #2386 Denver & Rio Grande Western #67598 #2387 Linde Industrial Gases LAPX #2199 #2388 Port Huron & Dertoit #1275 Penn Central surely had some old Pennsy X-29s left, and we’ve covered NYC. Canadian National had some boxcars for similar dimensions in the 503500-513152 series. New Haven had some INSULATED boxcars with 8’6” inside height. D&RGW didn’t have cars of these dimensions in 1954. And Port Huron and Detroit did not own ANY cars in revenue service in 1954. The Linde boxcars are not really boxcars but BOXTANKS, so the Register does not give inside dimensions. I could not determine whether Linde had any boxtanks in X-29 type bodies. From the 1940s, they housed their internal tanks in bodies almost identical to 1937 AAR specifications, except that they did not have the “tabs” along the side sill where car sides connection to underframe crossbearers. That’s because the whole box superstructure was made to be removable. Atlas A1g Linde boxtank on Irwin’s http://www.irwinsjournal.com/a1g/a1g_2387.jpg Like all the prototype Linde boxtank photos I have found, the Atlas A1g is “correct” (ie conforms) in having a straight side sill without the “tabs” or gussets on the side sills. I built an approximate model of one of the later Linde boxtanks that had the 1937 AAR-type superstructure. I used a Concor 40’ steel boxcar, filed away the half-ladders on the right sides of the ends, removed the “tabs” from the side sills and added a strip along the bottom to make it more or less straight. Also added a little piece of plastic on the end of the car to represent end doors used to access certain valves, etc on the internal tanks. Would have been better if I had inset the little door into the Dreadnaught ribs. I used a Microscale decal. I understand there are some kind of hatches on the roof that I have never seen in pictures and I didn’t model. Anyway, if you HAVE the old Atlas A1g, it is somewhat like something real. I wouldn’t go out of my way to track down any of these old cars UNLESS I had a 1925-1950 MoPac layout, or I really wanted a corrugated end X-29. Just my druthers. Next we look at some newer, better quality X-29s, from three different manufacturers.
