The dynamics of dynamic braking A half-century ago, when diesel locomotives were replacing steam engines, a revolutionary breakthrough — dynamic braking — was making freight operations safer and more efficient. Dynamic braking is the method of train braking whereby the kinetic energy of a moving train is used to generate electric current at the locomotive […]
Diesel locomotive builders 1. American Locomotive Company For many years after World War II, Alco — the American Locomotive Company — was the second place diesel builder in the United States. The company’s history as a steam locomotive manufacturer dates from 1901. The Schenectady, N.Y.,-based firm began producing its first diesels in conjunction with suppliers […]
Train orders The train order, variously called the “flimsy” or the “tissue” — together with its attendant operators, train order offices, and order hoops — has been rendered obsolete by the radio, the computer, and amended work rules. With its passing in the late 1980s, so did a whole concept of railroad traffic control that […]
Railroad reporting marks Railroad cars are identified by two, three, or four letters and by a number of up to six digits. The letters, known as reporting marks, indicate the owner of the car, while the number places it in the owner’s fleet. Reporting marks ending in X indicate ownership by a private concern as […]
The year was 1978, and I was an assistant roadmaster for the Burlington Northern out of Lincoln, Neb. Through February, the winter weather had been mild and dry, and I’d mostly been overseeing repairs to several sets of outfit cars used to house production gang workers. On the first Tuesday of March, however, a […]
Rotary snowplow Snow … There are few things that mother nature can throw at the unsuspecting railroader that can wreak such havoc on operations. Those pretty little white flakes can blanket a landscape under an impenetrable frozen glaze, jamming the network and shutting down the main line. Fortunately, there are some tools in the railroader’s […]
General Electric’s U30C Up in the north woods of Michigan’s Upper Peninsula sits the last serviceable U30C — LSI No. 3009, dead and drained outside Lake Superior & Ishpeming’s diesel shop in Eagle Mills. This locomotive and its cousin, LS&I C30-7 No. 3073, had been filling in on ore trains when not enough LS&I AC4400CWs […]
I became a railfan at age three, near the end of World War II. Awaiting the return of my naval officer father, I sat in our West Philadelphia kitchen window facing one of the busiest divisions of the Pennsylvania Railroad — the four-track electrified main line to Harrisburg. The parade of wartime tonnage, plus express […]
Shortline railroading For many independent shortline operators, staying fiscally sound today means disregarding so much of what was once a winning formula. You know, picking up freight cars at the interchange and delivering them to customers, then dropping off outbounds back at the end of the workday before heading to the barn. If all went […]
U.S. Secretary of State William H. Seward must have thought he was making the real estate deal of a lifetime — 600,000 square miles for a cost of less than two cents an acre. That is the price Seward negotiated with Edouard de Stoecki, Russian minister to the U.S., for the purchase of what would […]
Locomotive power 2024 Someone turned on the new locomotive faucet, but its just a slow drip right now. For several years no new six-axle freight locomotives have been built for North America’s Class I railroads. Now, there are some signs of life. Last year saw orders from Canadian National and BNSF Railway — Canadian National […]
More than a few times, photographs in the Kalmbach library have sent me searching for railroads and places I’ve never encountered, and a few weeks ago some 8 x 10 prints lined up perfectly with travel plans. The destination: Mendocino, Calif., the charming old lumber town up the coast 155 miles from San Francisco. My […]
