a train consisting of self-propelled carriages that are powered by electricity from overhead lines or third rails
An electric multiple unit (EMU) is a type of train that is powered by electricity and consists of multiple carriages or coaches that are connected together. Each carriage in an EMU has its own electric motor, which allows the train to move without needing a separate locomotive. EMUs are often used for passenger services, particularly on suburban or intercity routes, because they are efficient, fast, and can accelerate quickly. They are commonly found in cities and areas with busy rail networks, providing a reliable and environmentally friendly mode of transportation.
- Electric multiple units are commonly used in urban transit systems for their efficiency and ability to handle high passenger volumes.
电动多单元因其效率和处理高乘客量的能力而常用于城市交通系统。
- EMUs are equipped with motors in each carriage, allowing them to accelerate and decelerate quickly, which is advantageous for frequent stops.
电动车组每个车厢都配备有电机，使其能够快速加速和减速，这对于频繁停靠是有利的。
- Unlike traditional trains pulled by locomotives, EMUs distribute their propulsion power across all carriages, making them more energy-efficient.
与由机车牵引的传统列车不同，电动车组将其推进力分布在所有车厢上，使其更加节能。
- Many modern EMUs feature regenerative braking systems, which capture energy during braking and feed it back into the power grid or store it for future use.
许多现代电动多单元配备有再生制动系统，该系统在制动过程中捕获能量并将其反馈回电网或储存以供将来使用。
- EMUs are often preferred for short to medium-distance travel due to their reliability, ease of maintenance, and reduced emissions compared to diesel-powered trains.
电动多单元由于可靠性高、维护方便且与柴油动力列车相比排放减少，通常被首选用于短到中距离旅行。
