But I do not have good info on details such as tank car manufacturer
type (e.g. 11, 21, 27, etc). If that exists let me know and I'll search
for it - there is a wealth of data in this site - it could use a full
word index system for quicker and more accurate searches.

Tank cars - (Information from Tim Gilbert summarizing the January 1943 ORER)
Union Tank Car Co. 38,707
General American Transportation Co. 27,867
Pennsylvania-Conley Tank - div. of GATX 10,327
Shippers Car Line 6,949
Sinclair Refining Co. 6,447
AT&SF 3,567
US War Department 2,475
SP - Pacific Lines 2,219
Gulf Oil Co. 1,551
UP 1,096
Dupont 1,068
Sun Oil Co. 1,035

However, given that the ORER does not allow us to decipher types, and tank
car companies were notorious for mixing cars from multiple makers into
series, the best I think we can do is try to convey the impression of the
WWII fleet.

Some rules of thumb -
-UTLX had the biggest fleet so the X-3 would likely be the most common
tank (Lots of Sunshine kits!) and IIRC, the 8K size was NOT the most
common (10K?)

-AC&F production of type 21 cars outnumbered type 27 by a significant
margin, and the 8K size was the most common of the type 21s.

-GATC built tanks were fairly common and we have no reasonable model in HO
for a fleet.

-"Oddballs" such as the UTLX "van Dyke", and earlier type 7 and 11 tanks
should not appear in great numbers, but were certainly in use.

So, for now, a fleet of Sunshine and Walthers/P2K tanks with a few
Intermountain, Precision Scale, Speedwitch (NATX tanks), IM/Tichy bashed
USG-A, Southern Car and Foundry (STC cars) and whatever else I've
forgotten (like the RC brass GATC cars and other brass cars) will make a
reasonable fleet with the exception of missing GATC cars. Like boxcars,
this approach will give you the varying sizes and features seen in WWII
era "pipelines on rails"

See my other post, but I thought most WWII era refineries were north of
the gulf - the off-shore oil had not been developed yet.

During WWII, the tank cars and pipelines carried crude oil and not refined
products to the refineries in the NE. Those fields, as others have noted
were onshore fields in Louisianna and Texas.
