To mark the 50th anniversary of the Staatsspoorwegen in the Dutch East Indies, the line between Batavia (today Jakarta) and Buitenzorg (today Bogor) was electrified in 1925. Direct current with 1,500 volts was used and the required locomotives were obtained from different manufacturers in the Netherlands, Germany and Switzerland. For use in front of express trains on the flatter routes, four six-axle locomotives were used, the mechanical part of which came from SLM and the electrical part from BBC.

The Java bogie was used for the first time on these locomotives, which SLM later successfully used on several locomotives. In addition to the two driving axles fixed in the middle of the frame, there was one of these bogies at each end of the locomotive, each consisting of a leading and a driving axle. The pivot point was close to the driving axles, so that the one-sided Buchli drive could also be attached to these driving axles. 

In the years 1924 and 1927 two of these vehicles were delivered each, which were given the numbers 3001 to 3004. At the KAI they were later given numbers 1 to 4. They remained in service throughout their lives on the same line and were retired in 1976 after being replaced by Nippon Sharyo EMUs.
