Lucerne for precise checking and relubrication. The average speed was 62 kilometres per hour (39 miles per hour), with a pure driving time of 21 hours and 51 minutes, which was considerable for the time. On the 26 ‰ inclines, the train travelled at between 55 and 60 kilometres per hour (34 and 37 miles per hour). In a start-up test, the train could reach the required speed in 2½ instead of 4 minutes. The permissible temperatures were never exceeded during the entire test phase.

Between 23 and 24 September 1922, number 12328 was used to confirm the specification had been met. The test train with a weight of 302 tonnes (297 long tons; 333 short tons) was driven from
Lucerne to Chiasso and back three times in 25 hours. After the second return trip, a one-hour stop was set up

The design of the locomotive was derived from Be 4/6 12302, particularly the first batch, numbers 12303 to 12312. Traction was provided by two electric motors, one mounted in each bogie. The motors drove two drive axles. Each bogie also had an unpowered running axle. Wheels had between 2 and 70

on draft design proposals submitted for ten locomotives to be numbered 12303 to 12313. A follow-on order for 12313 to 12342 was placed in July the same year. An important criterion for the order was an even distribution of passenger and freight locomotives from the different companies.

was part of a general trend moving the locomotives to the lowlands. However, they required an ever-increasing amount of repair and maintenance, and retirement started in April 1965 with 12312, with locomotive number 12339 the last discarded in
February 1976.

Locomotives 12313-12316 were delivered to Bern from 12 January 1921 to 19 July 1921, and were then transferred to
