The El 11 is an electric locomotive of the Norges Statsbaner (NSB).
The series was built in two series and is based on designs by the SLM (bogie) and BBC (electrical control). The 11a series was built between 1951 and 1956, the El 11b series was built in 1963 and 1964. Visually, the two series differ in the front panels, which are four-part in 11a and two-part in 11b. The 11b series also has the same electrical equipment as the El 13 and multiple controls . In addition, 11 2083 and 2090 received the two-part windshield after accidents.
operation area
It was built as a universal locomotive and used in front of both passenger and freight trains.
The 11 2092, 2098 and 2110 were given a different gear ratio in 1982–83 for use on the Flåmsbana so that they could perform at their best at 30 km / h. The motor was also improved so that it could withstand the braking current of 1000 A for a longer period of time, and magnetic rail brakes were also installed.
Retirement
As the first El 11, 11 2150 was shut down in the same year after a collision on December 2, 1970 in Oslo Østbanestasjonen . Also as a result of accidents, 11 were hit in 2083 and 2090. Between 1994 and 1998, the remaining El 11 were retired.
The three locomotives for the Flåm Railway were replaced by the El 17 in 1996 .
