Valve Gear Info Valve gear on a steam locomotive is used to control the admission of steam into the cylinders of a locomotive. Specifically, the valve gear controls the timing or duration of time boiler pressure steam is allowed into the cylinders. For efficiency reasons, you would only want steam to be admitted into the cylinders during the short "intake" portion of the stroke which would allow the steam to expand throughout the "expansion" portion of the stroke. However, for maximum power when starting a steam locomotive from rest, boiler pressure steam would need to be admitted almost throughout the entire expansion portion of the stroke. Because of these changing conditions, the engineer needs to be able to control or adjust the valve gear which changes the timing of steam admission. This was done using a large lever (often called "The Johnson Bar") in the cab.

Southern Pacific Transportation Company The Southern Pacific Transportation Company (reporting mark SP), earlier Southern Pacific Railroad and Southern Pacific Company, and usually called the Southern Pacific or (from the railroad's initials) Espee, was an American Class I railroad. It was absorbed in 1988 by the company that controlled the Denver and Rio Grande Western Railroad and eight years later became part of the Union Pacific Railroad. The railroad was founded as a land holding company in 1865, later acquiring the Central Pacific Railroad by lease. Column - My Modular Adventure: Roundhouse weathering Dorman64, Thank you for your comments. You are perfectly right; this all started out as an article about an operating TT and roundhouse which would be published in two or three articles. Well, as you so rightly observed it is quite a lot more than that.

4-12-2 "Union Pacific" Type Locomotives In the mid 1920s many western railroads were using the 2-10-2 and 2-8-8-0 type locomotives for mainline freight trains. These locomotives were getting the job done but were limited to about 20 mph. The Union Pacific Railroad experimented with a three-cylinder 4-10-2 in 1925 and actually bought ten of them. These 4-10-2 locomotives were capable of slightly greater speed while being capable of pulling about 20% more tonnage. The UP wanted more and approached the American Locomotive Company with a design for a 4-12-2 and received the first of this new design in 1926. SoundTraxx Welcome to the SoundTraxx Tsunami Preview!

How to make villages for model train layouts How to Make villages for model train layouts In this series of hobby videos, you will learn how to create accurate layouts of model train villages by comparing them with vintage photos. Make villages for model train layouts - Part 2 of 16 UP Heritage Steam During World War II Union Pacific operated some of the most modern and powerful steam locomotives ever built. Among them were the famous "Big Boys," the largest steam locomotives in the world, which were unique to Union Pacific. Working with them were the slightly smaller "Challenger" freight engines and the "800-class" high-speed passenger locomotives, as well as hundreds of older class steam engines.

RIDING THE CAB FORWARDS When I was a young boy around ten years old I rode up front with the engineer and fireman in the cab of a fully operable freight hauling Southern Pacific Railroad 4-8-8-2 cab forward locomotive, one of the largest most powerful railway steam engines ever built --- and I rode in one not just once, but twice. The first time was with my older brother on the slightly down angle 50 mile straight-on set of rails in California's high desert out of the community of Mojave. The 100 car plus train was heading southbound towards Los Angeles, the locomotive's 63-inch drive wheels sometimes wavering along the distantly mirage laden tracks howling at flatout speeds approaching 90 miles per hour. Detailing an Alley By Christopher Brimley Occasionally, when doing a little city planning on your layout, you find extra space between your buildings. There are a few remedies for this space, such as sizing the block to fit the buildings perfectly, kitbashing or scratch building a structure to fit, or leaving the hole open for an alley. I purposely plan alleys because they add a large amount of visual appeal and break up the monotony of a row of buildings. Whatever the era of your layout, you can easily detail an alley to blend in.

ATSF 2-10-4 5021 The 5011-class 2-10-4's were the last steam locomotives purchased new by the Santa Fe. They were war babies, built in 1944 at a time when freight dieselization on the Santa Fe was well underway. Due to wartime materials shortages, the War Production Board imposed strict controls on new locomotive purchases, particularly diesels. Santa Fe was awarded the lion's share of road freight diesel production in the form of EMD's FT, but it still wasn't enough to meet the railroad's needs.

Cheap Junk By T.W. Rimer All photos by T.W.
