NSB Class 73 - Specifications

Specifications

Class 73 is a four-car electric multiple unit built by Adtranz. Each train consists of eight bogies—of which three are powered—with a total power output of 2,646 kilowatts (3,548 hp). The trains have active tilting, which allows speeds 20 to 30 percent higher than conventional trains through curves on conventional lines. Maximum permitted speed is 210 km/h (130 mph). A four-car train is 108.48 meters (355.9 ft) long; an A-series weighs 215.1 tonnes (211.7 long tons; 237.1 short tons) while a B-series unit weighs 216.1 tonnes (212.7 long tons; 238.2 short tons). The trains have a steel body and the entire cabin is pressurized. Rail brakes are installed on all carrying bogies.

The A-series has a capacity of 207 seated passengers, while the B-series has room for 250. The difference is caused by the B-series having a smaller bistro and more compact seating. In the A-series, each of the four cars has seating in a different color (blue in BFM73 car, green in BMU73, red in BFR73, and yellow leather in BM73 and in the bistro area in BFR73). Originally, three of the cars had floors with carpet, while the fourth car (BFM73) had vinyl, of consideration to people with allergies. The carpets were removed in about 2005 as it was difficult to keep them clean. Seating is in two classes, standard and Komfort (originally "Plus"); the latter (BM73 car) with leather seating and power supply for laptops. All the cars have cherry tree wood interior. The trains are equipped with a dining section (BFR73 car) and warm meals can be served at the seat or in the diner. The menu is according to the time of day, with breakfasts in the morning and larger meals in the afternoon and evening. The trains also feature a family section with a play area and HC area (BFM73 car). The BFM73 car has also a bicycle room behind the driver's cab. From 2011, the trains are equipped with free wireless Internet.
