dc series motor :A series-wound DC motor has a low resistance field and armature circuit. Because of this, when voltage is applied to it, the current is high. (Ohms Law: current = voltage/resistance). The advantage of high current is that the magnetic fields inside the motor are strong, producing high torque (turning force), so it is ideal for starting a train. The disadvantage is that the current flowing into the motor has to be limited, otherwise the supply could be overloaded and/or the motor and its cabling could be damaged.
knuckle threads are used in railway carriage couplings.
Hydraulic motors are commonly used in military vehicle wheel motors, crane drives, high powered lawn trimmers, and winches. William Armstrong was one of the first to construct a hydraulic motor.
I-sectional beams are used in railway tracks because the strength to weight ratio is excellent. They are also used because they have extra area which allows for stiffening of the metal without extra materials.?æ
Pneumatic valves are used to close valves in high-speed internal combustion engines, pneumatic valves are mostly to help racing engines to get to high speeds.
Steam engines were first used in the tin mines of Cornwall, England to pump water from the mines which often extended out under the Cornish coastline.
Steam isn't typically used for locomotives anymore. Normal operation of a locomotive is the generation of electricity with the use of an engine-generator set, often a diesel engine. This provides electricity for traction motors that turn the wheels of the locomotive. Excess electricity is stored in batteries, which provide power to the traction motors when the engine is not running, often to reduce noise and pollution in areas, such as cities, where it is undesirable to produce such noise and pollution.

In delhi metro used motor is INDUCTION MOTOR.
Yes, oil is used to lubricate internal combustion engines. Grease is used to lubricate electric motors. =========================================================== I have always used non detergent oil in my ELECTRIC MOTORS and grease for the bearings if there is a grease fitting
steam is used on things such as railway engines and standby generators.
Some used steam-powered engines, others used early petrol or gas engines. Some even used battery-powered electric motors.
Oil can be used in various motors or engines to power them along and gas can be used on a stove to start a fire.
GM did make 2 stroke diesel engines used in trucks and busses..they were noisy, requierd a super charger to run, loved to drink but very powerful.
a railway is a track with engines it can be a mountain railway or just a railway * Added - A railway is a fixed guideway system (vehicles cannot leave the track) and can be powered by gravity, animals (including people), stationary engines, or locomotives (any vehicle that is self propelled). A train is a "consist" of multiple vehicles designed to move on the railway. As the term is used in conventional use today, a railway includes the track and all other wayside equipment, all the vehicles, stations, shops, and control centers.
No, because there's no oxygen in space for the engines to use. The rocket motors used to go into space are supplied with combustion oxygen via the engines' plumbing.
GM replacement engines are very similar to the engines used in those trucks, but not exactly the same.
