Hi List Members,
For your viewing pleasure, a nice shot of UTLX 59762 photographed at Denver, Colo., May 21, 1935. http://cdm15330.contentdm.oclc.org/cdm/singleitem/collection/p15330coll22/id/67212/rec/4417 Note the differing dome construction and safety valves. If this is in fact a multi-compartment car, I cannot really see where the compartment divider bulkheads are positioned... maybe the vertical rivet rows on the tank nearest to the outward domes? - Claus Schlund |

March 21 I have an answer about where the bulkheads are located. First, it helps to recognize this tank as being a 4 course. The 4 sections are full length, from head to head with no splices. Non of the radial rivets are seams joining adjacent sheets such as would be found on radial circumferentially constructed tanks. Each double row of vertical rivets is retaining a single bulkhead. There are gaps between the bulkheads (No single bulkhead separates any two compartments). This tank car has 6 bulkheads, including the two end caps. Total gallonage will be quite a bit less than the original single compartment capacity because of the air gaps between each adjoining bulkheads. -Andy Carlson Ojai CA

From the June 1936 Tank Car Capacities volume, UTLX 59762 is listed as being 6591 gallons. (A compt. 2190 gals., B compt. 2211 gals., C compt. 2190 gals.). Domes are 107 gals./275 gals./109 gals. respectively. Ian Cranstone Osgoode, Ontario, Canada |

Nice picture, of an interesting car! Just guessing from the uneven dome sizes, I suspect this may have been rebuilt from a single-compartment car. The large center dome would be the original, and big enough for the whole car. Each of the smaller outer domes would be only large enough for its own compartment. If each tank has convex heads, it's possible that *both* rivet rows between each pair of domes are partitions. Somewhere I've seen a photo of a three-compartment tank car which lacked outer sheathing between the partitions, so the three tanks had space between them -- strange-looking indeed.

There's one here: This is a car built by Canadian Car & Foundry in 8/1920 for Imperial Oil. Earlier orders looked to have some sheet steel applied between the tanks to at least make it look like a larger tank, such as: http://nakina.net/photos/supx/supx002006.jpg Ian Cranstone Osgoode, Ontario, Canada lamontc@... http://freightcars.nakina.net http://siberians.nakina.net |

You're going to face-palm on this one. UTLX 59762 is a longitudinal 3-course tank car, not a radial course car. You can just see the top rivet seam in the photo. Thus, the two rows of double rivets on the sides are BOTH the compartment dividers.
I also note the "INFLAMMABLE" placard, the 7-34 reweigh date, K-brakes, side mounted safety valves on the end compartments and the car number on the B-end side sill. Alas, no repack or test dates are visible so there is really no way to check on the
photo date of 1935.

Claus, your post prompted a lot of needless guesswork. In fact, this was an 8K gal. UTL X-3 which had been converted into a three compartment car, leaving the original dome for the center compartment and adding smaller domes (with side-mounted safety valves, because there wasn’t room for them on top) for the end compartments. UTL had a sizable number of similar cars, and General American had even more; I have numerous photos of cars from both owners which had been similarly converted from single compartment cars (and even a couple of photos of asymmetrical cars with a smaller compartment added at only one end). The only thing unusual, though not unique, about this car is that there was more air space than usual between the internal diaphragms (essentially tank ends) that separated the three compartments. Thanks for calling attention to this nice photo. Richard Hendrickson |

March 21 Actually, Bruce, This is a 4 course car (see the row of rivets at the very top of the tank). -Andy Carlson Ojai CA

Hi Richard and everyone else who
replied,
If I wrote down everything I know about tank
cars it would all fit on the back of a postage stamp! I am happy to have
the chance to learn more.

Ehrrr... if this was a four course car, it would have horizontal lap seam in the upper quadrants of the sides, like the much maligned Gould/Tichy tank car. With a central top seam, that indicates two upper sheets and a floor sheet.

Thanks, Dennis. I was going to point that out as well. UTL X-3s all had three horizontal course tanks, with the exception of a very few short 8K gal. cars built very early (ca. 1917) in the history of the X-3 design. Richard Hendrickson |

The Pacific Electric Rwy in SoCal used a similar
arrangement in their Arrowhead Water Tank Cars about this same period.
