EMU

Emu trains, or electric multiple units, are trains that consist of self-propelled carriages that can be coupled together. Unlike locomotive-hauled trains, emu trains do not require a separate engine or power car to move. Instead, they draw electricity from an external source, such as overhead wires or a third rail, and use traction motors to drive the wheels. Emu trains are more efficient, reliable, and environmentally friendly than diesel trains, as they produce less noise and emissions, and can accelerate and brake faster.

Emu trains have been operating in the UK since the early 20th century, and have become the dominant type of train on electrified routes. They are used for various types of services, such as commuter, intercity, regional, and high-speed rail. Some of the most common emu trains in the UK are the Class 390 Pendolino, which runs on the West Coast Main Line at speeds of up to 140 mph, the Class 800 Azuma, which runs on the East Coast Main Line and the Great Western Main Line at speeds of up to 125 mph, and the Class 700 Desiro City, which runs on the Thameslink network across London and the South East. Emu trains can also be found on other routes, such as the Crossrail, the Merseyrail, and the ScotRail.
