Class 374

The British Rail Class 374 is an electric multiple unit operated by Eurostar. It is currently branded as the Eurostar e320. Part of the Siemens Valero family, it is the successor to the Class 373, Eurostar's original fleet of trains. While some Class 373s are being retained for a limited range of services, the modern Class 374 will lead Eurostar into the future.

In many ways, the Class 374s are vastly superior to the aging Class 373s. The high-tech Class 374s can operate to new destinations across Europe such as Amsterdam and Frankfurt, something the Class 373s are not capable of as they not have the space to install the necessary signalling systems.
