Take a close look at a reproduction 1880 dual gauge A frame gallows turntable at the Great Western Steam Up at the Nevada State Railroad Museum in Carson City.
This type of turntable was in use in the 19th century when locomotives were smaller. Later turntables were steel bridge monsters for turning the massive locomotives of the twentieth century. These early turntables were made of wood and turned by hand!
The weight of the locomotive is carried on a "spider" at the center of the turntable. The ends float requiring that the locomotive be placed in the exact center of the turntable bridge.
We also take a look at an On3 model of a gallows turntable built by Steve Strebel. An excellent scratch-built model it shows the workings of the center "spider".

Another excellent video, thank you. To everyone wanting to know why we are missing the outer ring, the answer is that a few years ago a high speed chase ended when the suspect accidentally drove into the pit! The cops caught him when he had to flee by foot. The outer ring had been damaged by the getaway car, but it had also been settling unevenly over the past 30 years which made turning it quite difficult, so it provided an unexpected opportunity to rebuild the ring using the very early Southern Pacific design to just do without the outer ring and just pour a concrete pad for the ends to rest on. If you email the NSRM about it, ask for pictures!

Thanks love the information. We noticed the concrete around the ring was brand new! That explains that. I’m glad they were able to arrest the ringleader.

Of course a true early version would’ve been stone or perhaps wood cribbing, but we need to be pragmatic sometimes. Have you ever seen a gallows-type table made of steel? I’m considering turning one of my F-Scale steel Howe truss bridges into an outdoor turntable, but I’ve never seen that style executed in full-size before so maybe you could enlighten me?

The lead you describe as the place to store the shop switcher, or dinky, as we call it, is actually for loading or unloading equipment from trucks. The Antelope and Western locomotive was unloaded there. Last August the tender for the Glenbrook was loaded and unloaded there for it's trip to the Cumbres and Toltec. The table works quite well. A few years ago, I turned the 34 ton McKeen car by myself. That's me on the lead platform of the 10 car going by. There are similar tables at the museum in Laws California and in Folsom California.

Thanks! Love to see one person turning the McKeen! Once I grabbed the hand grab of a C16 tender (223) as we needed to move it about 200 feet. I was waiting for 10 or so people who were going to help push but for fun I just gave a mighty pull. And here comes the tender. It’s amazing how low friction is on rails.

One of my friends and fellow parishioners at my church had a bit to say about the old school railroad workers and booze, so here we go: My friend Denny went to work for Missouri Pacific RR when he finished his contract with the USAF in 1970. When he was getting switcher training in KC, his trainers/supervisors said to keep working the yard and staging trains while they went to lunch. Two hours later they came back from lunch with two 12 packs of falstaff beer in each hand, and also were drinking them while on the job training my friend Denny and operating in said rail yard. So even in 1970, railroad crews were still drinking heavily.

@ToyManTelevision 2 жыл бұрын

I wrote a fun paper sometime back. I took the amount of alcohol which we assumed was consumed by a track crew, worked out the number of people working on each section of track. And then figured out an amount of beer that was consumed per mile when track was being laid. Then divide that by scale. It came out something like drinking one beer for every 10 ties when handling in your track!!

The ring with the wheels is called a spider. Under a turn span bridge, the wheels were cone-shaped(and much smaller in diameter to save space) so that the focus of the conical rays is at the center of the bridge. This type of arrangement was also used under turntable bridges. Most of the larger and later turntables were designed as 2 simple spans supported by the ring rail and the spider so that the turntable bridge did not have to be so long.

Hi again. Years ago I built an HO scale carousel. The spider that makes the horses go up and down it’s almost identical to the spider on one of these gallows turntables. I still have that carousel around here somewhere. But it was badly damaged in a move. Anyway it was pretty neat. Being HO scale the whole darn thing was only about 7 inches across. Three rows of horses and they all went up and down. Three rows and I believe 8 sets. About 30 lights. Music.. shame it a bit broken.

Unfortunately Steve has said about tearing apart the new rail road as well. He keeps selling off sections and turning sections into dioramas and selling off the dioramas. He does have a long-term plan that wants the entire attic is empty he’s going to turn it into the ultimate shop and then just work on individual projects. But stuff that doesn’t take up a lot of room. Like a single structure or a brass engine.

Hi all I do turntable demonstrations at the Colorado railroad museum. with there arm strong Turn Table . And it has the ring rail and wheels. And i can turn by myself with D R G W #491 on it At around 90 tons . Those wheels about 1 in off of that rail at both ends if it is off balance and those wheels touch the rail it takes 4 to 6 people to turn it.

@ToyManTelevision 2 жыл бұрын

Yup. The key in low friction from metal wheels on rails. And balance. I once pushed a C16 tender by myself and in fact it was easy. Amazing!! It’s the key to all railroads.

@ToyManTelevision 2 жыл бұрын

Well it helps. But the basic reason is turning the turntable moves the common rail from one side to the other. The only other way to make it work would be to build a transition in the turntable bridge so the common rail moves from one side to the other. But the simple way is a four rail bridge.

I can clearly see why it’s an A frame turntable. Those cables form the shape of an A. Makes sense eh? I didn’t think the operation of it as an Armstrong man powered turntable it was so difficult to operate. It’s all about balance. No rail to rotate like the modern turntables.
