They are not always reverse.
If the train had 96 cars and one engine for every 24 cars, you would divide the total number of cars by the number of cars per engine to find the number of engines. So, 96 cars divided by 24 cars per engine equals 4 engines. Therefore, the train had 4 engines.
In the days of steam engines each engine had its own crew, engineer, fireman and usually brakeman. Diesel engines have only one engineer in the lead unit, the others are controlled from the lead engine. Even the engines in the middle or rear end of the train are controlled from the lead engine in most cases.
The pulling capacity of a train engine depends on various factors such as the type of locomotive, the number of engines in the consist, the grade of the track, and the condition of the rail. Generally, a single train engine can pull hundreds to thousands of tons of freight or passenger railcars.
Yes, if the the engine is a steam engine or a diesel engine. The diesel engine smoke should be almost invisible when the engine is in good condition. Electric locomotives are not typically called "engines", but these do not produce smoke.
Piston engines vary from little 1 cylinder engines that power a weed trimmer or leaf blower to HUGE 12-18 cylinder engines that power a large ship or a railroad train. There is no one answer to your question. A piston engine can weigh a few ounces to many tons.
One can purchase a toy train engine at the popular retailer Toys R Us. These engines are also available at Walmart, Just Kids Store,Target, Hobby Lobby and Railway Toys.
The engine on a train is behind the driver.
trains diesel engines are far less powerful as they just run an electric generator that powers electric motors. container ships require a much larger engines that turn live (mechanically connected) shafts that turn propellers.
As it relates to internal combustion engines, the oil pressure must be sufficient to express oil from the related orifices, and pump it to the engine heads at the top of the engine to lubricate the valve train.
The engine of an old train would be a steam engine.
work on a train as a general helper, assiting passergers with basic needs.
The weight and length of the train, as well as the incline of the terrain it will traverse, are key factors that determine the number of engines needed. A heavier or longer train, or one traveling through hilly terrain, may require more engines for sufficient power and control. Additionally, the speed at which the train will be operating can also influence the number of engines needed.
