Berliner Verkehrsbetriebe (BVG) launched the first pre-series Type IK U-Bahn train from Stadler Pankow on February 3.
Ordered in 2012, the Type IK is intended to replace the 1970’s A3L71 on Berlin’s narrow-profile U-Bahn lines U1 to U4.
The tighter profile of these lines has previously restricted train widths to 2.3m, but the Type IK features a curved mid-body that increases internal space by 100mm, giving a total overall width of 2.4m.
The pre-series cars will initially run on a dedicated track, followed by at least two months on the network without passengers before entering service in May for a 12-month trial. If successful, BVG has committed to a firm order for a further 34 sets from 2017.
