Re: Tangent GATC 8,000 Gallon 1917-Design Radial Course Tank Car

Is 49125 one of the 12K X-3 cars mentioned above. This car looks like the Red Caboose model on steroids. Also attached is DODX 12100, the class from which the RC model represents. This would be substantially the same car as the UTLX 39000 series.

Yours Aye,

Garth is correct, I did overlook a couple of line items, which I will add below in Red.

Nice list, but you forgot that UTLX bought 500 welded ACF 10K cars in 1951, their series 39000-39499. Richard Hendrickson identified the often-lamented Red Caboose model as a suitable representation of these cars.

I suspect that I have done this exercise a time or two before.  There is much more detail in the UTLX book.  Personally, I am drawn to model 1952, so it is good to have both the UTLX record and the 1955 Tank Car Tariff to make comparisons.


In round numbers in 1952, UTLX rostered about 41,000 tank cars.  The listings below account for about 38,000 of those and don’t include very small, very large or multi-compartment cars.

12,000 gallon Class X-3                    620 

12,000 gallon Class X-3W                500

10,000 gallon Class X-3                   10,561

10,000 gallon Class X-3W                500

8000 gallon Class X-3                       1923

6500 gallon Class X-3                       3838

10,000 gallon Class X                          972

8000 gallon Class X                           3156

6,500 gallon Class X                            605

10,000 gallon Class X-4                     493

11,000 gallon Class X-5-300           5302

11,000 gallon Class X-5-400             391                       Total UTLX design cars   28,861 cars

10,000 gallon Class Z                        3431

8000 gallon Class Z                           6761

11,000 gallon Class Z-5-300             382                       Total non-UTLX design cars          10,574 cars          Total      39485 cars


The only HO models of the UTLX design cars were/are the resin kits from Sunshine Models and, more recently, from Resin Car Works.  The Red Caboose 10,000 gallon welded tank car is quite close to the UTLX X-3W design.


UTLX purchased, new, at least 1000 of the 8000 gallon GATC designed cars (the Tangent car) and certainly acquired others of these through second hand purchases in the 1930’s.  They also purchased, new, some from Standard Tank Car Company, both 8000 and 10,000 gallon cars.  (Southern Car and Foundry underframe, but need horizontally riveted tanks.)


Second hand 8000 and 10,000 gallon ACF tank cars (the P2k Type 21 models) were also added to the fleet during the 1930’s.  There were almost no ACF Type 29 tank cars (the Intermountain cars) among the second hand purchases by UTLX.


Mostly in the rush to expand the roster of high pressure tank cars following WWII, UTLX also purchased ACF designed Z-5-300’s, like the Kadee car.

From all of Elden's research here in the archives, wouldn't GATX be more common than UTLX on these General American cars? I have more UTLX than I should, thanks to the P2K offerings, and not enough GATX which was the largest fleet circa my 1953. I have GATX decals coming from Black Cat.
