A train is a series of connected vehicles that run along a railway track and transport people or freight. Locomotive helps to pull or push the train. Nowadays, the train is an easy, fast and affordable way of transportation. From the invention of the train to the day, various innovations made it faster. Today we can see high-speed trains, which transport people and freight from one place to another. To make it more efficient various parts of a train are manufactured and assembled precisely. So many companies manufacture the train like Siemens, Alstom, etc. So, in this article, we will see all train parts, their function & names.

Parts of a Train
The function of the diesel engine is to generate power from the combustion of the diesel in the combustion chamber to drive the train.
The diesel engine is big and has various systems and arrangements to increase efficiency. Generally, it is present in the front carriage of the train.
It is a metallic tank for storing and supplying fuel to the engine to generate power. The tank consists of a thousand gallons of diesel in the tank. It is necessary to have more diesel for the long journey.
A turbocharger is a forced induction device powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine to produce more power for a given displacement.
The alternator’s function is to generate AC electricity to drive the traction motors of the train. Input rotational power comes to the alternator through the engine drive shaft to develop the electricity.
Its function is to generate electricity which we can use in the train to operate fans, lights and charging ports.
Bogie is a chassis or framework that carries a wheelset attached to a vehicle—a modular subassembly of wheels and axles. Bogies range from one axle to four or multiple axles.
Two-axle bogies are the most famous due to their adequate performance in the curve tracks and ability to handle heavy loads. Its alternate name is the truck.
The air conditioner is necessary to maintain the temperature in the different compartments like 2-tier & 3-tier. It consists of a compressor, condenser, expansion valve, evaporator, etc. AC is available in fixed carriages only.
A coupler is a mechanism generally placed at each end of a railway vehicle that connects them to form a train. Designing these types of coupling is a complicated and challenging job.
The countries like India, South America & Europe mainly use chain and buffer couplers, whereas the rest of the world uses knuckle couplers.
As we know, the railway is a robust and large steel structure that is essential to stop at the stations. But with the conventional braking system, it is not possible.
Hence an air braking system is the best option. It uses compressed air as the operating medium. A braking system is available on the many train wheels, and air hoses supply the compressed air to each wheel for effective operation.
The Air compressor compresses the air and supplies them to the brakes. It drives the power from the alternator to operate. A reciprocating compressor is the best choice for locomotive applications.
An air reservoir is a highly thick metal storage device to sustain the high pressure and temperature of the air after compression. It is necessary to have a compressed air storage system to operate the air brakes. Without it, we cannot use the brakes on the locomotive or trains.
The cab is the train operator’s cabin from where he controls and operates the train. We get all types of controlling devices in a cabin to manage all operations on the train.
The control station is the dashboard where we can see all the controlling levers and buttons to control the train.
Coach is the general category like general, seater, sleeper, 2-tier AC, or 3-tier AC carriages. One coach forms multiple carriages.
A carriage is one of the separate sections of a train that carries passengers. It has seats, windows, and doors on both sides to enter.
Boxcars are big rectangular shape box comes with sliding doors on the sides. Its primary use is to carry large loads of products like grain, paper, flour, beverages, and other goods and protect them from harsh weather.
Insulated boxcars are insulated from all sides to maintain the inside temperature. These are specially designed for carrying and storing the products like vegetables, fresh foods, frozen foods, seafood, poultry, meat, dairy foods, and beverages.
Compartments are the sections inside the carriage. Each compartment is made of top, middle, and down seats depending on the type of train.
The communication cord is an emergency handle available in every train compartment to use in emergency conditions. Pulling this cord to deliver the signal to the train operator about the emergency is necessary.
The gearbox function is the multiply the torque and speed per the requirement. The power generated by the engine is high. It is necessary to control it and divert to the train wheel as required. So, the gearbox helps to manipulate the speed through the various gear arrangements.
It transfers the power from the engine to the compressor, alternator, and radiator fans for their work.
It is for attaching two passenger cars.
Inverters convert the electricity from AC to DC or vice versa.
It stores the electricity in chemical form to operate or start the diesel engine. It charges automatically when the train runs on the track.
Air intake allows the air to pass around the radiator tubes to cool the coolant. When air enters the air intake, it passes through the various filters to the radiator tubes. In the filter temperature of the air is regulated.
The radiator’s function is to cool the cooling fluid passing through the radiator tubes. When cooling fluid passes to the engine sides, it absorbs the heat and becomes hot. To reduce the temperature, it again passes to the radiator coils. This cycle repeats every time.
These are the fans around the traction motors to cool them.
As the name suggests, it blows air over the traction motors to keep them cool. This motor blower mechanism and construction are more complex for the new locomotives.
It stores the cold water and supplies them in the washrooms of the locomotive. It is filled before the train departs from its first station.
Toilet & Toilet Tank
It is for collecting human waste while traveling by train. In between the two carriages, a toilet is present. Human waste is gathered in the tank, and at the station, it is removed for the next journey.
A pilot is at the front of the locomotive to remove the obstacles from the track while the train is running.
These are the round, metallic, and tapered shape that drives the train on the track.
These are the ladders on the side of the train to climb to the top. During maintenance, it is allowed to climb on the train.
The fluid coupling transmits the power from the engine to the drive shaft. It consists of a stator, rotor, and casing.
The locomotive is the front portion of the train with an engine to produce energy for running the train on the track.
These are the large open container for storing and carrying the goods.
It is a box to contain sand, which can provide good adhesion to the locomotive in bad rail conditions.
Windows are for providing ventilation to the passengers. We can open them whenever we require, and these are usually sliding windows that slide up and down.
These are at the front of the train to illuminate the track and get proper visibility while driving.
It warns or gives an alert to the people who are standing in the station, road crossing, and on track. It improves the safety of the people.
It is a part of a train where you can buy food and drinks.
It is a space for eating food and drinking beverages.
It is a separate carriage that contains all the food, kitchen, and other food-related products. We can say it is a restaurant on the train.
The funnel is a tube on the top of the engine section to pass the smoke into the atmosphere. In the old train, we can find the funnels.
It is the passage inside the coach to walk.
It is a bed on the wall of the train that can swing down to sleep.
It is a shelf in the carriage to store the bags securely.
These objects hang from the train ceiling for holding through the hand.
It is present at the end of the train for observation purposes.
It is the top of the carriage to protect the passengers from bad weather conditions, rain, sun, etc.
