 Class 69 is a series of 88 two and three @-@ car electric multiple units built by Strømmens Værksted between 1970 and 1993 . A motor car has a power output of 1 @,@ 188 kilowatts ( 1 @,@ 593 hp ) , allowing a speed of 130 kilometers per hour ( 81 mph ) . Each car is 24 @.@ 85 meters ( 81 @.@ 5 ft ) long , with motor cars weighing 64 @.@ 0 to 53 @.@ 9 tonnes ( 63 @.@ 0 to 53 @.@ 0 long tons ; 70 @.@ 5 to 59 @.@ 4 short tons ) and end cars weighing down to 28 @.@ 8 tonnes ( 28 @.@ 3 long tons ; 31 @.@ 7 short tons ) . Typical seating capacity is 96 passengers in the motor cars and 112 passengers in the end cars . The class was delivered in four versions , named A through D. After the initial delivery of fifteen 69As in 1970 and 1971 , twenty 69Bs were delivered in 1974 and 1975 . These were designed to operate on longer sections and were equipped with only one door per car . This turned out to extend stopping time too much , and the C and D versions were delivered with two doors per car . From 1975 to 1977 , NSB took delivery of fourteen 69Cs and from 1983 to 1993 thirty @-@ nine 69Ds . The latter is distinguishable because of its different front . NSB operates both two- and three @-@ car sets , and up to three units can be run in multiple , allowing NSB to operate any train length from two to nine cars . Eighty @-@ two units remain in service ; although they have been retired from the Jæren Commuter Rail , NSB still uses them on the Oslo Commuter Rail , the Bergen Commuter Rail and the Arendal Line .
