Leslie S-5T train horn being fitted to a restored ex-Seaboard System EMD GP30 diesel locomotive at the 2006 Oak Ridge Horn Honk and Collectors Meet Train horns are made of multiple horn units called chimes which produce different notes; sounded together they make a chord. The Nathan model M5 pictured is a 5 chime horn.
Several distinct sounds are created by various parts of the train, such as engines, traction motors, brakes, and the wheels rolling on the rails. Roughness and irregularities on the wheel and rail surfaces are a source of noise and vibration. Rail joints and squats on the rail cause a familiar "clickety-clack" sound as train wheels roll over them.
A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel–electric locomotives and diesel–hydraulic.
A train whistle or air whistle (originally referred to as a train trumpet or air trumpet) is an audible signaling device on a steam or gas locomotive, used to warn that the train is approaching, and to communicate with rail workers. Modern diesel and electric locomotives primarily use a powerful air horn instead of a whistle as an audible ...
The American Locomotive Company (ALCO), based in Schenectady, New York, United States produced a wide range of diesel-electric locomotives from its opening in 1901 until it ceased manufacture in 1969. This is a list of ALCO locomotive classes. For individually notable locomotives, please see List of locomotives. There are numerous individual ...
The F3 used a 16-cylinder 567B series diesel engine developing 1,500 hp (1.1 MW) at 800 rpm. The 567 was designed specifically for railroad locomotives, a mechanically scavenged, or "blown" 2 stroke 45 degree V type with 567 cu in (9.29 L) displacement per cylinder, for a total of 9,072 cu in (148.66 L).
The EMD GP30 is a 2,250 hp (1,680 kW) four-axle diesel-electric locomotive built by General Motors Electro-Motive Division of La Grange, Illinois between July 1961 and November 1963. [2] A total of 948 units were built for railroads in the United States and Canada (2 only), including 40 cabless B units for the Union Pacific Railroad .
The ALP-45DP is an electro-diesel locomotive design, based on Bombardier's ALP-46/A and TRAXX locomotives. [ 40 ] [ note 3 ] Design requirements included weight less than 288,000 lb (131,000 kg), length less than 75 ft (22.86 m), and EPA -compliant emissions.
