UTLX X-3, 6.5K tank car
|
Chuck Cover
I recently built a Sunshine #62.5 UTLX X-3, 6.5K tank car. I was wondering if these smaller cars were used for any special/unique commodities or whether they were used in general service as most of the larger tanks cars were? I did not see any information about special uses in the paperwork that came with the kit nor in Essential Freight Cars:12 article. Thanks

There are liquids that are far heavier than water and petroleum. You can probably find out a lot online about chemicals without consulting any tank car information.

Nice photo Tim! Thank you for sharing. PQ Corporation still exists, and sodium silicate is a great example of a high specific gravity liquid (1.3 to 1.5 x heavier than water, depending on concentration). Also called water glass, it has uses in many industries, including the paper industry and agriculture, and was widely shipped by rail. As Tim notes, many acids and other chemical liquids are substantially more dense than water or petroleum. -- Jeff Helm |

Norm, thank you for pointing that out! I need to remember that you offer 1:87 decals. Would the new RCW 8k gallon X-3 tank be close to the PQCX cars? (Per Protocraft site, PQCX 108-110 built in AC&F lot 1603 in 1937)? The RCW cars appear to my untrained eye to be similar, other than brakes and dome relief valve details, but the prototype was built in 1927 & 1929, a decade earlier. Jeff Helm |

well you’re putting me on the spot here but they are certainly pretty similar - if they are both 8,000 gal

I’m still learning the nuances of tank car spotting features but gallon capacity becomes a math issue.

RCW kit noted has a 6,500 gallon capacity. Someone posted the Philadelphia Quartz lading would be 1.3 to 1.5 times the density of water. 6,500 x 1.3= 8,450 PQCX 110 is noted as having an 8,066 gallon capacity in the 1943 ORER. So it’s on the ballpark, but I have no dimensional data on the PQCX prototype to see how it matches the UTLX class X-3 6,500 gallon cars.

I think you’re mixing volume with weight - so a greater density just means that the 6,500 gallons will weigh 1.3 x heavier - but still 6,500 gallons - so my decal set unfortunately will still be for a 8,000 gallon tank car. Norm

Thanks, I was referring to the new RCW kit 4.04 8,000 gallon X-3. The Protocraft site notes an 8K capacity car, so perhaps I am not following? Density would not change physical volume, only the weight. -- Cheers Jeff Helm |

no - you are - I”m not - if both are 8m then we’re good

PQCX110 looks like an ACF type car to me. Better to start off with a LL Proto2000 8000k tank car. It would be pretty close. The UTLX cars were unique, though numerous.

Thank you, I definitely need to brush up on my tank car spotting features!

Ah, yes. It’s been many years since the college science courses. I haven’t had to apply volume calculations since then, too.

My apologies for an erroneous post. At least it sparked proper corrections! Eric Hansmann Murfreesboro, TN On Aug 7, 2022, at 12:00 PM, Norm Buckhart <norm@...> wrote: |

Thanks to everyone who responded to my request for more information on what a 6.5K tank car would normally carry. From what I have heard on the list, the car would not be any different than any other tank car so I guess I will put the car into general service on my operations based PRR Shamokin Branch layout. The model does stand out as it is so much smaller than the other tank cars, which is the reason that I decided to build it.
Thanks everybody who responded.

PQCX 110 is an 8000 gallon ACF Type 27 tank car. The InterMountain model is an exact match. But don't attach the bottom plat to the frame as these are two channels. Attached is a plan of the brake arrangment

Here we go again. This is like the discussiona few weeks ago on the FW&D covered hoppers color. This I gather has effected the sales of this otherwise excellent model. I don't disagree that the information is good to know, however, when viewed on a layout who will notice the difference? This is coming from someone who if there is a nick on the side of his car can see it from a block away and it is on the other side of the car. My fear is that there is currently a very few manufacturers of kits in the hobby. The time and effort and expense involved in producing a kit is monumental. To have all this effort trashed after the fact is quite discouraging. Who needs the grief? Remember that Gould was virtually driven out of the business after producing the best engineered plastic tank car model ever only to learn after the fact that the prototype was never made. I don't want to lose any more kit suppliers. What will we buy to put on a shelf never to be built?

Who is trashing them? So far I have seen reasonable critiquing which manufacturers should be open to. I don’t think that kit manufacturers should not be closed off from reasonable criticism simply because they could decide to stop producing.

Criticizing business practices is prohibited. Criticizing products is not. In this case we’re talking about a product that has been OOP for around 15 years.
