The total capacity is around 5,000 gallons of fuel. Usually two tanks, on each side of the locomotive. This train part is needed for the diesel engine to start, exactly as an automobile. Most of the locomotives in the United States have just one cab, at one end. In the United States, it is positioned in an angle on the left side. The area from which the locomotive engineer operates the locomotive/train. Rectifiers are used to convert the electricity from the main alternator from DC to AC.Ī truck, or also called bogie, is a frame, placed under the trains, onto which the wheels of the railway vehicle are fixed. The cooling system is way more complex, especially for the newer locomotives. Motor BlowerĪs the name states, the motor blower blows air over the traction motors, keeping them cool. This part is used for cooling the locomotive, the air is drawn inside the locomotive through these intakes, reaching the engine and other parts that need cooling, after passing through various filters and temperature regulators. The majority of passenger train locomotives are equipped with this extra alternator, where the freight locomotive doesn’t need it. – it’s mainly used to power auxiliary electrical sources, like the interior car lights, outlets, air conditioning, dining appliances. The diesel engine cylinders might be arranged in V or inline, where the engine engages the drive shaft for various tasks, including the most important, powering the alternator which produces the electrical energy to power the train. This type of locomotive it’s powered by the diesel engine, which powers the AC alternator. That’s why the locomotive it’s called Diesel-Electric Locomotive. The Main Alternator is powered by the Diesel Engine. The alternator generates AC electricity, used to power the traction motors. Please check the scheme created below for a general idea of where the parts are situated, note: this is for a general purpose only. I also recommend you to read what is a locomotive consist to understand things better. The Diesel-Electric Locomotive has over 27 major parts that contribute in harmony to its operation. So what are the parts of a train? Simple: Locomotives and Cars.Īs there are different types of locomotives and cars, go into the main details.Īs mentioned above I will go in depth on locomotive components, and I will analyze diesel-electric locomotive parts, diesel-mechanical, as well as the steam locomotive parts. In the past there was a third car, called caboose, attached at the end of a freight train, which stopped being used once the radio communications began to be implemented. These days, a train is a combination of locomotives and cars. Now I will run through all major and most minor parts of a train and include photos. As a railroad worker and a train enthusiast I remember how strongly I wanted to know what the parts of a train are and how they are all interconnected.
