The Class 175 Coradia is a special type of passenger train used in the United Kingdom. These trains are called diesel multiple units, which means they have their own engines and can run by themselves without a separate locomotive.
These trains were built between 1999 and 2001 by a company called Alstom. They were made at their factory in Washwood Heath, which is in Birmingham. Today, all the Class 175 trains are kept and maintained at a place called Chester Depot.

What is a Class 175 Train?
The Class 175 trains are part of the Coradia family of trains. This family includes many different types of trains used all over the world. The Class 175s are designed to carry passengers comfortably.
How Many Carriages?
These trains come in two main types. Some Class 175 trains have two carriages, which are called 175/0. Other trains have three carriages, and these are known as 175/1. Each train set can carry many people. The two-carriage trains can hold 134 passengers. The three-carriage trains can carry up to 206 passengers.
Where Do They Travel?
The Class 175 trains mainly operate in Wales and around the Manchester area in England. They are often seen on routes from Holyhead in North Wales, heading south. They also travel along the North Wales Coast. Many of these trains also run services around the busy city of Manchester.
Train Features and Technology
The Class 175 trains are built with strong steel bodies. They have special doors that swing outwards and then slide back into the train's side. This design helps save space on busy platforms.
Speed and Power
These trains can reach a top speed of 100 mph (160 km/h) (about 160 kilometers per hour). They get their power from Cummins N14 diesel engines. Each engine produces 450 hp (340 kW), which is a lot of power for moving the train. The power is sent to the wheels using a special transmission system.
Safety Systems
Safety is very important on trains. The Class 175 trains have two main safety systems. One is called AWS, which warns the driver about signals. The other is the TPWS. This system can automatically stop the train if it goes too fast or passes a signal incorrectly.
