The BVG Class HK is a type of electric multiple unit in service on the Berlin U-Bahn. It is operated by Berliner Verkehrsbetriebe (BVG) (Berlin Transport Company).
The HK is a Kleinprofil (small profile) variant of the larger Großprofil (large profile) H series.
Production history
In the early 2000s, Berliner Verkehrsbetriebe ordered twenty four-car small-profile HK class trains from Adtranz (merged into Bombardier Transportation during production). 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.[2] 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. [3]
Operational history
The HK series primarily operates on the U2 line.[citation needed]
