The Class 175 Coradia is a type of diesel multiple unit passenger train used in the United Kingdom. The fleet of 27 sets were built from 1999 to 2001 by Alstom at Washwood Heath in Birmingham. They are part of the Coradia family of trains along with the Class 180. They are the basis of Arriva Trains Wales's express fleet, but cannot operate on all lines (including those fitted with ETCS).
The entire fleet is owned by the Angel Trains. They were originally leased to First North Western, but the fleet has since been transferred to Arriva Trains Wales. For a brief period, units were also sub-leased to First TransPennine Express.
In September 1997, North West Trains placed an order with Alstom for 27 train-sets. The original order was for eleven two-carriage units with a top speed of 100 mph, seven three-carriage units with a top speed of 100 mph and nine three-carriage units with a top speed of 125 mph. This was reconfigured to eleven two-carriage and sixteen three-carriage units all with a top speed of 100 mph, worth £78 million, built to allow for the replacement of elderly Class 101 'heritage' DMUs and locomotive-hauled trains to Bangor and Holyhead. As they were constructed, the old locomotive sheds at Chester were replaced with a purpose-built facility in order to service the Class 175 units. Units were tested at low speed at the Severn Valley Railway before further testing and driver training at the Old Dalby Test Track from November 1999. The first unit entered service on 20 June 2000.
The two-carriage units are numbered 175001–011, and the three-carriage units 175101–116. Carriages are labelled as coaches A–B–C, with two-car units having no coach B. Each train has provision for two disabled passengers in coach A, and storage for two bicycles in coach C.
