Say you’re an engineer running a multi-unit diesel consist on a freight train. During the trip, it becomes necessary to remove the lead unit because of a grade-crossing entanglement, some mechanical problem, or to give to another (underpowered) train. No problem – the second unit can lead as well as the first, so you resume […]
Who controls the movement of the trains after the tower is closed? The train dispatcher is the most common heir to the towerman’s duties, but not always. The type of control used depends on the nature and density of the rail traffic handled at the location. Ways to preventing trains from colliding when railroad lines […]
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 […]
TO CROSS THE Rocky Mountains, the Union Pacific railroad was always looking for the next big thing. This eye toward innovation gave rise to such notable giants as the 4-8-8-4 Big Boy, the 4-12-2 Union Pacific, the massive DDA40X diesel, and the turbines. In 1952, the Union Pacific received the first of 10 4,500-horsepower turbine […]
THE PENNSYLVANIA RAILROAD’S famous 4-4-4-4 Duplex drive T1 locomotive, designed by Raymond Loewy, epitomizes the rakish, spaceship look of industrial design in the late prewar years. If the locomotive’s outline looks familiar it should: its shape has been reproduced on thousands of calendars, artwork, and even non-railroad-related advertising. The Pennsy ordered two prototype Duplex-drive locomotives […]
MOUNTAIN RAILROADING is a tough job in North America. In the last century both the Great Northern and Milwaukee Road utilized electric locomotives to master this beastly job. The grades of Washington state’s Cascade Mountains were a tough nut to crack for the Great Northern. The first Cascade Tunnel was built in 1900. At an […]
WAY BACK IN 1965, I showed Joe, my next door neighbor, my prize birthday present: a James Bond Shooting Attaché Case (made by MPC, no less). Joe, a grownup insurance salesman, opened it up, smiled, and said, “Boy, Bobby, you could commit mayhem with this!” Opening the box for the Operation Iraqi Freedom train set, […]
WHEN ANDREW’S RAIDERS tried to steal the Western & Atlantic Railroad’s General locomotive during the Civil War, they certainly had no idea how many fantasy “great locomotive chases” they’d inspire in the decades to come. Lionel, for one, has had great fun with the concept. When the Lionel Corp. produced its postwar nos. 1862 and […]

Tower 55 is a subsidiary of Overland Models, a manufacturer of brass locomotives and rolling stock. The Explorer-series locomotive reviewed here includes an […]
Atlas HO scale EMD MP15 Here’s a great looking, smooth-running model of Electro-Motive Division’s versatile MP15 heavy-duty yard switcher. At first glance it may look like any other EMD switcher, but this one is a hauler capable of moving up to 42 free-rolling cars on straight, level track. Atlas offers the MP15 in a Silver-series […]
WHO HASN’T HAD the daydream? You buy the local branch line railroad and find a small switcher, and next thing you know, you’re the Commodore Vanderbilt of your town. But if your dream came true, chances are that your business plan (and wallet) would probably call for an industrial switcher, not an SD90MAC diesel. Industrial […]
