In the early 2000s, Berliner Verkehrsbetriebe ordered twenty four-car small-profile HK class trains from Bombardier Transportation. Four pre-production trains underwent trial service for three years before being fully adopted. The completed trains were delivered to Berliner Verkehrsbetriebe between mid-2006 and the end of 2007.[1] The vehicle bodies feature aluminum shells, with modular roof, cab, and underframe components. The power draw of the HK variant is 1,020 kW as compared to the larger H series 2,160 kW. [2]
Operational history
[edit]The HK series primarily operates on the U2 line.[citation needed]
