Electric Locomotive EG 1 K.Bay.Sts.B.

In 1912 the Königlich Bayerische Staatsbahnen started to electrify the first tracks. Out of the first 17 electric locomotives, there were two which technically speaking distinguished themselves from the conventional ones and then proved to be extremely innovative. Whilst in those days electric locomotives usually had the well known side rod drive from the steam locomotive, these two machines already had a single axle drive, as is standard practice nowadays with all modern electric locomotives. Single axle drive means that every driver axle has its own electric motor.

Both locomotives were ordered in 1912 and supplied in 1914 and 1915 by Krauss (technical vehicular components) and Bergmanns Elektrische Werke (electric components). They were stationed in Freilassing and put into service on the hilly route between Freilassing and Berch-tesgaden. Both locomotives were originally designated as EG 4 X 1/1 in accordance with Bavarian customs. 

With an overall weight of 56 t they were able to produce a maximum tractive force of 9,300 kg, whilst the maximum speed was set at 50 km/h. They proved to be outstanding, a replica build of this locomotive or development of the drive concept however didn’t happen initially, it was only 20 years later that the single axle drive made its breakthrough. The locomotives were obviously ahead of their time.
