The January 1955 ORER gives 30' IL, 9'2" IW, and 11'2" height to eaves. These are uncommonly tall and skinny hoppers for the 1950s. After thinking about it for a bit and playing a hunch, the ten cars

July 1950 gives 25 cars in series 5000-5491, no individual numbers. January 1953 is down to five cars: 5039, 5144, 5191, 5391, 5396. David Thompson

Looks like an insulated high-pressure tank, so ICC class 105 most likely. The Atlas or Kadee tanks are a good starting point. The logo on the side is for Smith-Douglass, a Norfolk,VA-based fertilizer

The Union Oil tanks look almost like UTL Type Xs, with the obvious exceptions of the headblocks and center yoke around the dome. The tank bolsters are also different, though a similar design. David Th

I compiled some info from Pennsylvania Tank Line's ORER entries the last time this topic came up: Pennsylvania Tank Line first appears in the February 1912 ORER with a picture of PTX 1001: https://pla

YS&T 110 is the type of car that Pennsylvania Tank Car was building in the early-mid Teens. The car behind it appear to be an early (pre-1917) GATC tank. David Thompson

ACF's tanks before the Type 27 tended to be shorter lengthwise for their nominal gallonage?? (and therefore larger in diameter) than most of the other tank car builders. What you want for that Milwauk

Probably a load shifted/fell over enough to dent the door. David Thompson

Yeah, I think it does.?? End drawing for 49500-49999 here: https://www.nwhs.org/archivesdb/detail.php?ID=20569 Compare to 48000-48999: https://www.nwhs.org/archivesdb/detail.php?ID=4113 David Thompson

I trust the 49000-series B-5 will come with the Superior door option? https://www.nwhs.org/archivesdb/detail.php?ID=19398 David Thompson

Looks like 15500-15749 is your series. David Thompson

Aha! That hint and a quick search turned up an article in the February 1906 American Engineer and Railroad Journal, pp. 52-53. https://books.google.com/books?id=lEmxCGAbOSEC&pg=PA52 https://books.goog

This was apparently somebody's sample car, built June 1897, that ended up as P&LE 3: https://historicpittsburgh.org/islandora/object/pitt%3A8223.1896.RR https://historicpittsburgh.org/islandora/object
