Car trucks and carbodies Do you remember running boards and full-height ladders on box cars? They are known in the railway supply trade as freight-car components, and while running boards and full-height ladders have followed the telegraph key and the steam locomotive into railroad technological history, other components remain as key elements of the freight […]
Leslie and Nathan may sound like a dull couple from the ‘burbs, but they’re actually the first chairs in railroading’s horn section. The diesel locomotive horn section, that is. Many of today’s train-watchers recognize a railroad by the sound of its diesels’ horns. It’s only natural since sound is a strong memory-jogging sense, second only […]
Locomotive classification lights Locomotive classification lights — colored flags by day, lights by night — were once used throughout North American railroading. U.S. railroads used a single light and outer lens, with colored lenses in between that could be changed as needed. Canadian roads used three separate lights; on diesels these were often located near […]
Ruling Grade: The maximum meaningful grade on a line; the grade that limits train tonnage. Traditionally, a ruling grade was the grade up which the standard road locomotive assigned to that division could just stagger with a maximum-tonnage train. This grade may not have been the steepest on the division, however. There may have been […]
Outfit cars Cars equipped with facilities for feeding and housing construction and maintenance employees in the field are known as outfit cars or camp cars. Over the years they have taken a number of forms. Because outfit cars are not revenue-producing equipment, railroads have tended to not spend much money on them, and a common […]
Virtually all the railways in the world employ the same system for moving the vehicles that travel over them: Power is applied to some or all of the wheels that support and guide the vehicle along the rails. Adhesion between the wheels and running rails then allows the vehicle to move along the track, often […]
Perhaps no part of railroading is as important as that which gave the industry its name: rail. Together with flanged-wheel vehicles, rails allowed the development of a transport system quite distinct from the conventional roadway. Though rails of steel are standard today, iron and even wood found widespread use in the 19th century. Many early […]
Traffic control systems Running a safe operation is not as simple as you might think. Every train must have authority to occupy the main track before it can begin moving. There are several types of authorities, but usually only one type is in effect on any given piece of track. Maintenance people must also have […]
Because shippers’ distribution patterns are rarely congruent with any one rail carrier, railroads have developed two traditional methods of extending their reach over each others’ lines. The first is the joint rate and route. Two railroads, by agreement, establish one rate from an origin on the first to a destination on the second. One of […]
In 1920, when American railroads emerged from 26 months of government control, the prevailing philosophy of freight-train operation was to hang as many cars as possible behind a locomotive and send it out to drag its way along the line. Three locomotive types were ideal for drag freight: 2-10-2, 2-6-6-2, and 2-8-8-2. The 2-10-2 and […]
Wabash No. 2924 was the last of the road’s 25 4-8-4s, all built by Baldwin in 1930. Classic Trains coll. The Wabash of 1900 was part of the empire that George Gould inherited from his father Jay. Its lines linked Detroit, Toledo, Chicago, St. Louis, Kansas City, Omaha, and Des Moines, and formed major hubs […]
