Intercity 125 (train)

The Intercity 125, also known as the Class 43, is a high-speed train that has been a key part of the UK's rail network since the 1970s. Designed for fast, long-distance travel between cities, it features powerful diesel engines and streamlined design to achieve speeds up to 125 mph (201 km/h). Its distinctive tilting mechanism allows it to travel smoothly on curves at high speed, reducing travel time and increasing comfort. The Intercity 125 has been an essential workhorse for intercity services, known for its reliability and speed, and has influenced modern high-speed train design.
