Produced from 2014 to 2018, the Siemens BR Class 700 serves solely with Thameslink of England.
The BR Class 700 EMU is an Electric Multiple Unit designed, developed, and built by Siemens Mobility of Germany. The train set is related to the Siemens "Desiro City" family of diesel and/or electrically-driven trains utilized primarily for daily high-speed passenger service. The type is used throughout Europe with operators seen in Austria, Belgium, Bulgaria, Czechia, Denmark, Germany, Greece, Hungary, and Slovenia. Outside of Europe, the train can be encountered in Malaysia, Russia, Thailand, and the United States.

The BR Class 700 sees Thameslink (owned by Cross London Trains) as its sole operator. It depots at Hornsey (of London) and Three Bridges (of West Sussex). It was selected as a direct replacement for an aging line of different models that included the Class 319, Class 365, Class 377, and Class 387 types. The series was constructed from 2014 to 2018 to the tune of 115 total units. Operational service followed on June 20th, 2016 and continues today (2023).

The fleet encompasses two distinct marks in the Class 700/0 and the Class 700/1, differing in formation (cars per unit, and thus passenger capacity) and train set weight. The Class 700/0 has eight cars in its formation and can ferry 427 seated passengers while the Class 700/1 has twelve cars across its formation with seating for 666 (this does not include standing passengers during Rush Hour segments).

The Class 700/0 carries Serial Nos. 700001 to 700060. The Class 700/1 carries Serial Nos. 700101 to 700155.

The cars measure 66.2 feet long with a beam of 9.1 feet. Floor height reaches 43.3 inches. Total weight of the Class 700/0 train is 278 tons. The Class 700/1 follows at 410 tons. The driver is seated at front-left in the lead car behind a wide-view front windshield. Access to the cockpit is via side doors. Headlamps are positioned to either side of the bow with an overhead installation also present. A windshield wiper keeps the front windshield clear of rain, snow, and debris. Passenger entry / exit is made available by double-leaf pocket sliding doors of which two are affixed per side of every car.

The all-electric-drive train is powered by a 25kV 50Hz AC overhead system accessed via Pantograph assembly and a 750V DC third rail accessed via contact shoe. This propels the train to speeds of 100 miles-per-hour (160kmh). A Siemens IGBT arrangement serves as the train's traction system. The Class 700/0 outputs at 4,400 horsepower while the Class 700/1 increases to 6,700 horsepower.

The braking system is comprised of a disc-based electro-pneumatic / regenerative arrangement. Safety systems include ATO, AWS, ETCS, and TPWS.
