Here's an interesting picture for at least two of us. Maybe more. That's a T43 being delivered to Aberdeen Proving Ground for testing. Date appears to be March 25, 1952. The big flats weren't

Nice model Dan! Didn’t Roco make two versions of USATC Flats….the one pictured and another with straight sides? AMTRAK got a bunch of them and likely used them to move locomotive and passenger

While in the future of this list, I photographed several M103s on flat cars in Anniston, GA during a Southern Steam Excursion from Columbus, GA in about 1975. Thanks! — Brian Ehni From:

The M-103 was a most impressive vehicle. The first pilot model was completed in 1949, but the productionmachines didn’t appear until 1953, so it’s right at the end off the steam-era. For more info

In 1949, the T43 heavy tank was approved for development. It eventually became the M103 heavy tank, of which 300 were built. They weighed about 65 tons. One fits nicely on the 100 ton flats that are

And they are up to their usual standard, they all came with two brake types so you can put the right one for your era on the car. Jeff White Alma IL

Guys; Interesting topic. I read much correspondence, also on how many M-4’s you could fit in a cargo ship, vs. larger tanks. Bruce is correct, and I’d also add that until Leslie McNair

Hudson, While size may have played a role (in addition to offloading capabilities, there were concerns about mobility, infrastructure strength, etc… with heavier tanks), probably the biggest

The M4 tank was a Medium tank and one of the reasons that the US did not field a Heavy tank was that the M4's weight was just about the maximum capacity of the onboard ship cranes of the era. -Hudso

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

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

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

The 1947 and 1948 CB&Q ORER’s listed 40 U.S. Army boxcars (24167, 24169-24182, 24184-24186, 24190-29195, 24197-24210) as operated under lease by the CB&Q. They were 37’ 9” outside length, inside

Bruce Smith is spot on about USAX (later DODX six-axle flat cars). They were manufactured in 1953 to handle the Patton family of tanks, which were considerably heavier than their predecessors. Prior

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. Dan

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

It is my impression that the barrel of the M115 (8" howitzer) is not a smooth bore, but rifled. From TM 9-1300-203, page 2-143: "The projectile [8-Inch: HE, M106] consists of...and a gilding metal

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

No M-47 tanks in Korea. The M-47 was a crash program to put a better turret on the M46 Patton tanks following obvious shortcommings found in the Korean conflict. The M-47 was strictly post-war. Korea

You forget the M75 APC. https://en.m.wikipedia.org/wiki/M75_armored_personnel_carrier Thanks! Brian Ehni (Sent from my iPhone)
