The Class 424 is a class of electric multiple units in use on the Hanover S-Bahn network.


They are similar to Deutsche Bahn's Class 425 and Class 423 trainsets, but feature a comparatively low floor height of 78 cm (31 in) to allow step-free access on 76 cm platforms. They also lack a third set of doorways in the center of each car.
