After 17 months of works, on 31 October the EUR40m, 2.7km (1.7-mile), five-stop tram extension from Adlershof to S-Bahn Schöneweide opened for passenger service on lines M17, 61 and 63. The first tram was GT6ZO 2211 on line 63.
Line M17 now runs Falkenberg – S-Bahn Adlershof; line 61 is now S-Bahn Schöneweide – Rahnsdorf Waldschänke and line 63 is Landschaftspark Johannistal – Mahlsdorf. Nine trams/hour are provided in each direction.
The new line runs through a partly-undeveloped area, but also serves commercial and residential premises and the site of Berlin’s first aerodrome, now a park. A total of 7.4km (4.6 miles) of overhead was installed by Furrer+Frey.
As the route crosses a water protection area, the grass track is equipped with STRAILastic encapsulation on a sub-ballast mat to absorb noise and vibrations. A rail head conditioning system is installed on curves to lubricate the track with a synthetic oil to counteract rail squeal. A 500m3 rainwater retention tank is being installed under the new tram and bus interchange at Schöneweide.
Project funding came from the Berlin Programme for Sustainable Development and the European Regional Development Fund as well as the Berlin Senate. On the opening day rides were offered using Tatra KT4D 219 282/481, 7011+7012 and T6 5117+5563 museum trams. Older heritage vehicles also made an appearance.
