The Class 387 Electrostar is an electric multiple unit (EMU) built by Bombardier Transportation for Great Northern,Gatwick Express, c2c and Great Western Railway (GWR), with the first delivered in December 2014.

These trains are part of the Electrostar family which also includes classes 357, 375, 376, 377, 378 and 379.

The Class 387 is an evolution of Bombardier’s Class 379 Electrostar with a higher maximum speed of 110 mph (175 km/h). This has allowed UK rail network operator Network Rail to release additional paths to train operators on routes with line speeds up to 125 mph (200 km/h).

The first Class 387/1s were ordered for the Thameslink route, which enabled the existing Class 319s to be transferred to Northern Rail for use on the newly electrified Manchester Victoria to Liverpool via Newton-le-Willows route.
