52,090 in 1911.
When two of the locos (no. 1 and 3) were transferred to Norges Statsbaner in 1920 after NSB took over Tinnosbanen, where they were designated El 7 and numbered 2501 and 2502.

It returned to Drammen in 1936 and remained there until it was taken out of service in 1956; RjB 6 was retired in 1960, the rest remained in service with Norsk Transport in 1966 when they were replaced with NSB El 1
