The MVG Class B is an electric multiple unit (EMU) train type operated by the Münchner Verkehrsgesellschaft on the Munich U-Bahn system.

Initially the prototype units couldn't operate in multiple with full production trains due to differences of their electrical systems.

[1] The interior of the Class B is largely similar to the interior of its predecessor, the MVG Class A, consisting of transverse seating bays in 2+2 configuration, providing seating space for 98 passengers, with additional standing space for 192 passengers per twin unit.

[1] In 2006, Siemens bought prototype unit 498 and refitted the southern-end car 7498 with Syntegra-bogies to create a demonstration vehicle.

The unit has been tested at the Test- and Validationcenter Wegberg-Wildenrath in North Rhine-Westphalia,[3][1] and entered revenue service on August 13, 2008.

[1] After the removal of all reusable parts, the car bodies of unit 498 were sold to the Bahnwärter Thiel in October 2018, where they will be repurposed as a cafeteria and workspaces.
