to my opinion cables and wires are the most important and used component , even in motors the wires + current will produce the magnetic field that moves it

Most of railways and Metros are working on 25KV AC system. Therefore, common equipment would include Single phase transformers, series motors & degenerative breaking systems. Auxiliaries will include DC distribution system with battery bank back up.

In modern transportation, diverse electrical components are essential for safety and efficiency. Electric motors power vehicles, trains, and buses, contributing to sustainable mobility. Traction systems drive railway locomotives using overhead lines or electrified rails. Signals, communication systems, and control systems regulate traffic and coordinate operations. Power distribution systems ensure energy flow, and lighting systems enhance visibility. Navigation and GPS aid route planning, while ticketing and security systems streamline passenger processes. Elevators, escalators, and Automated People Movers improve accessibility in transportation hubs. Charging infrastructure supports electric mobility, and air traffic control systems

In Africa, as in many other regions, the most common electrical equipment used in transportation systems are:Electric Trains and Trams: Electric trains and trams are widely used for both passenger and freight transportation in various African countries. They are more energy-efficient and environmentally friendly compared to diesel-powered trains, making them a preferred choice for many urban and intercity rail networks.Traffic Signals and Street Lighting: Traffic signals and street lighting systems are essential for road safety and urban infrastructure.

An example I have seen is a DC to DC converter (DC Chopper). A DC chopper converts fixed DC voltage to a controllable or desired DC output voltage.

A power converter in transportation vehicles may also be known as a traction converter. The primary purpose of a traction converter is to create a suitable output for the traction motor, which is the propulsion source for the vehicle. Traction motors are controlled by various methods, but the ultimate goal of the traction converter is is to control the traction motor in proportion to the driver control inputs. The traction converter interprets signals from the driver, and converts the electrical input from the power source into an electrical output for the traction motors.

This is a superb explanation as it best shows the basic definitions of electrical terms used in the field of Electrical Engineering.

In transportation systems, power converters play a vital role, with inverters being essential for converting DC to AC in electric vehicles. Rectifiers are commonly employed to convert AC power from the grid to DC for charging infrastructure. Boost converters increase voltage levels for efficient energy transfer in trains and trams. In aviation, aircraft power systems often utilize variable frequency converters for onboard electronics. Power electronic devices like IGBTs and MOSFETs are integral components for efficient power conversion in various modes of transportation. These converters collectively contribute to optimizing energy flow and distribution in diverse transportation applications.

Typically, in battery vehicles, DC is converted to an AC output to the traction motor. This DC to AC converter is known as an inverter. Typically, in a hybrid vehicle, the engine generator provides AC to the traction converter. AC is converted to a fixed DC voltage. This AC to DC converter is known as a rectifier. The part between the rectifier and the inverter is known as the DC-Link. When manufacturers discuss voltage levels in electric vehicles, the DC-Link voltage is the voltage they often talk about, and is where the battery is connected to. The rectifier is controlled to create a fixed DC-Link voltage and the inverter is controlled to create the correct traction motor output in proportion to the driver inputs.

Control Systems is what differentiates an advanced transport mechanism to a basic bicycle. Essentially they are the brains. For example, lane auto correction. There are sensors that would tell your transportation system if you are within you lane and steer towards the inside of lane if you go out of lane. The more advanced your transportation is, the more complicated your control system begins to look like.

Control systems in transportation play a vital role in ensuring the safe and efficient operation of vehicles. These systems utilize sensors to monitor various parameters, such as speed, temperature, and environmental conditions. Actuators, like throttles, respond to control commands to adjust critical aspects of the transportation system. Controllers process sensor data and make decisions, while feedback loops help maintain stability and accuracy. In essence, control systems are the intelligence behind transportation systems, enhancing safety and performance.

In transportation systems, common electrical equipment includes electric motors for vehicle propulsion, control systems for managing functions, and sensors for monitoring various conditions. Power converters and inverters manage electrical energy, particularly in electric vehicles. Batteries and charging systems are key for energy storage, while signal systems ensure safe rail and urban transit operations. Overall, electrical systems complement other systems that enable everyday transportation (such as mechanical and industrial) it’s important for everything to work together to enable the infrastructure that is the backbone of our society, something that we often take for granted.

As an electrical engineer, I emphasize the paramount significance of control systems in transportation. These systems, employing sensors, actuators, controllers, and feedback loops, play a pivotal role in monitoring and regulating vehicle operations. A speedometer, functioning as a sensor, measures vehicle speed, while a throttle, an actuator, manages fuel or air supply to the engine. Controllers like cruise control maintain desired speeds by adjusting the throttle based on speedometer readings. The feedback loop continuously compares actual output with desired, ensuring dynamic corrections for optimal system performance. Mastering control systems is imperative for refining precision and efficiency in diverse transportation applications.

In today's transportation landscape, a wide range of electrical equipment plays a crucial role in shaping a more sustainable and efficient future. Electric vehicles, including cars, buses, and scooters, are becoming increasingly common, supported by an expanding network of charging infrastructure.

And also RFID (radio frequency identification) can be used in order to tracing the stuff. And gps is also needed for this system

Electric trains and trams, electric aircraft for short-haul flights, and electric boats and ships are also making transportation greener. Signals and signaling systems, trolleybuses, and electrified rail systems ensure safe and reliable travel. E-mobility components, such as batteries and motors, underpin the electrification of transportation, while intelligent transportation systems enhance traffic management. These advancements collectively contribute to a cleaner and more connected transportation ecosystem.

Some other examples of electrical safety and protection devices used in transportation systems are circuit breakers, fuses, surge protectors, ground fault circuit interrupters, and arc fault circuit interrupters.

Additionally, the integration of smart and connected technologies is a key aspect of modern transportation systems. Electric vehicles are often equipped with advanced driver assistance systems, while traffic management systems use real-time data to optimize traffic flow and reduce congestion. Electric mobility platforms and apps enable users to plan routes, access charging stations, and seamlessly navigate urban environments. These technologies not only enhance the convenience and safety of transportation but also play a vital role in reducing energy consumption and emissions in our increasingly electrified and interconnected transportation networks.

Telematics: Systems that combine telecommunications and informatics, often used in connected vehicles for tracking, communication, and data exchange.

In my experience, the most important piece of equipment is my safety PLC and safety rated sensors. Designing the fail-safe functions to bring a train to stop is the single most important aspect of the entire system. What if something fails? How do I prevent harm to passengers? Solving all of your hazards is the baseline to your entire control system.
