The British Rail Class 820 is a type of tri-mode multiple unit to be manufactured by Hitachi Rail for Grand Central. Based on the Hitachi A-train design, 9 five-car units will be built, powered by 25kV 50Hz electrification, as well as battery and diesel power.
On 3 April 2025, Grand Central announced plans to order a fleet of 9 new five-car tri-mode trains.
In March 2026, it was announced that Grand Central's new fleet will be known as the Class 820 under TOPS. The fleet will cost ã300 million and is to be financed by Angel Trains, with the fleet being built by Hitachi Rail at its Newton Aycliffe Manufacturing Facility.
The first deliveries of the Class 820 are planned for 2028 and will replace Grand Central's Class 180 fleet.
