a type of train composed of self-propelled carriages powered by diesel engines
A diesel multiple unit (DMU) is a type of train that is powered by diesel engines and consists of several connected carriages, each with its own engine. Unlike traditional trains, which require a separate locomotive, each carriage in a DMU can move independently, allowing for more flexibility and quicker acceleration. DMUs are often used on regional or local passenger services, especially on tracks where electric trains cannot operate. They are popular in areas with less frequent rail service or where it is not practical to build electric rail infrastructure, providing a reliable and efficient way to transport passengers over medium distances.
- DMUs are commonly used for regional train services due to their flexibility and efficient operation.
柴油多单元由于其灵活性和高效运行，常用于区域列车服务。
- The diesel multiple unit travels at moderate speeds, making it suitable for short to medium-distance journeys.

- Passengers on a DMU can enjoy a relatively quiet ride compared to older locomotive-hauled trains.
与老式机车牵引的列车相比，柴油多单元列车上的乘客可以享受到相对安静的乘坐体验。
- In some countries, DMUs have replaced older steam-powered or electric trains on branch lines.
在一些国家，柴油动车组已经取代了支线上老旧的蒸汽或电力火车。
- The design of a diesel multiple unit allows for easier maintenance and lower operational costs compared to traditional locomotives.
柴油多单元的设计相比传统机车更易于维护且运营成本更低。
