Re: Late 40's to mid 50's military rail movements
There’s some confusion in the statement "DODX six-axle flat cars were manufactured in 1953 to handle the Patton family of tanks, which were considerably heavier than their predecessors”. Tanks indeed were getting heavier, and a 6-axle car was in order to better transport them. But that wasn’t exclusively because of the “Patton” tanks. The progression of tanks from WWII was … 1) M-4 Sherman family, about 35-38 tons; 2) M-26 Pershing, about 45 tons; 3) M-46 Patton (an upgraded Pershing), about 45 tons; 4) M-47 Patton (an upgraded M-46 with an all new turret), about 45 tons, 5) M-48 Patton (an all new tank in 1952), about 47 tons.

Thus the substantial increase in weight occurred with the M-26 Pershing, which didn’t go into widespread use until 1946, after WWII. So, it was the M-26 Pershing tanks that "were considerably heavier than their predecessors”. The follow-on M-46, M-47, and M-48 Pattons were not significantly heavier than the Pershings. The M-26 Pershing was not widely used until the Korean conflict in the early 1950s and this was when the substantial need for a higher capacity flatcar would have been felt, and later met, with the 6-axle cars. So it was the M-26 Pershing tank in 1946, followed in 1949 by the similar M-46 Patton tanks, that led to the 6-axle cars in 1953. Dan Mitchell ==========

New RPM Announced: Batavia New York, April 3 2022
G.J. Irwin
I'm helping to spread the word about a new Railroad Prototype Modeler's Meet scheduled for April 3, 2022 at Batavia, New York (about halfway between Buffalo and Rochester). It will be held in conjunction with the Great Batavia Train Show at the Genesee Community College's Richard C. Call Arena. It's being sponsored by the Lakeshores Division of the NMRA and the Genesee Society of Model Engineers, a club located near Batavia. They had a table at today's train show to publicize the coming event.
Attached (I hope!) is a PDF with more information. If you're an RPM in the area, I'm sure they'd be happy to have you aboard! Cheers, George Irwin

Pure speculation on my part: the war was over and the army did not need the cars. But the pent up consumer demand had been released and the railroads had beaten many cars to death during the war, so they needed cars. The government got a little cash (likely "little" given how cheaply they disposed of war surplus) and the railroad got some cars at a bargain rent. Richard Townsend

Re: Late 40's to mid 50's military rail movements
I now believe you are correct. Early howitzers were often smooth bore, and fell somewhere between “guns” (rifled) and mortars (smoothbore). By WWII even the howitzers were rifled.

The Army bought 6300 M59 APCs between 1954 and 1959, they would
appear in our time frame. The only model of them I am aware of is
a 3d printed one at $18.00 each IIRC. One of my modeling goals is to model the movement of an Armor Battalion. I've been buying up M47s, trucks and Roco flats for several years as it's a pretty expensive proposition. All of the Roco flats need to be repainted OD and relettered with the Mt Vernon decals.

It is my impression that the barrel of the M115 (8" howitzer) is not a smooth bore, but rifled.

Re: Late 40's to mid 50's military rail movements
The M75 was not an artillery tractor or truck, as we’ve been discussing. It was an armored personnel carrier, and it was developed very late in the Korean war. Only a small number saw service in the last year of that conflict. As such it is only “just” a “steam era” vehicle.

Korea was fought initially with WWII tanks, the M-4 Sherman and M-26 Pershing. Later the M-46 Patton (an improved M-26) came on the scene. They also used M-36 and M-18 Hellcat tank destroyers, and all the artillery pieces we’ve been discussing. For transport thay had most of the WWII trucks and tractors and a couple newer models. Anything much beyond these is NOT “steam era”. Dan Mitchell ==========

Just remember that M-60 tanks and M-113 Armored Personnel Carriers are post steam era 1960's and later stuff. They don't belong on this steam era group.

Re: Late 40's to mid 50's military rail movements
The gun shown is the M1 (later M2) “Long Tom”. It was the largest of three variants of the 155mm gun, having a tandem-axle, 8 tire main chassis, and (usually) a 2-wheeled limber for the gun trails (early versions hooked the trails directly to the towing Mack NO truck). This is a true “rifle” with a 22 ft. long rifled barrel. For its size it was quite mobile, and widely used in both the WWII European and Pacific theaters. It was also used in Korea. Much the same gun also appeared in self-propelled chassis as the M-40 (and earlier as the M-12 with a shorter barrel).
toggle quoted messageShow quoted text
There was also the 8” (203mm) howitzer version with the same chassis, but a shorter, "fatter” smooth-bore barrel. The two barrels were interchangeable on the chassis. Then there was the version we have been discussing, the M-114 howitzer, with a short (11 ft.) 155mm barrel and a single axle (2-wheeled) carriage. It was much lighter and more mobile, but had less range. All these could be towed behind heavy trucks (7-ton or more, Mack, Diamond-T, Brockway, White, and Corbitt), or the so called “high speed tractors”: the 8-ton M5, the 18-ton M4, and the much larger 38-ton M6 (used mainly for the huge 240mm gun).

Re: Late 40's to mid 50's military rail movements
Quite possible. While most everyone is familiar with the famous GMC CCKW “deuce-And-a-half” 2.5-ton trucks, there were MANY other WWII trucks larger and more powerful. Thes included Diamond-T 4-tons; Mack NO 7.5-tons; White, Corbitt and Brockway 10-tons (virtually identical); and a few even larger (the big Diamond-Ts, the Ward LaFrance, and Pacific’s "Dragon Wagon”). Most all were 6X6, and ALL were often used to pull trailers and towed artillery. So were many variations of the half-track vehicles.
toggle quoted messageShow quoted text
Roco made HO models of the WWII CCKW 2.5-ton, and the Corbitt 10-ton (rare HO model), and also the M4 high speed tractor and the Pacific “Dragon Wagon”. Artitec offers WWII HO CCKW trucks (nicer than the Roco version). Dan Mitchell ==========
