The ESS 3200, later the WH 200 (Werkspoor-Heemaf)[citation needed] was a class of electric locomotives built for the Staatsspoorwegen, the State Railway of Dutch East Indies (modern day Indonesia).

[1] The ESS 3200s were of the 1-Bo+Bo-1 wheel arrangement, used a 1,500 V DC overhead catenary, producing 765 kilowatts (1,026 hp).

They were built by the Werkspoor using Baldwin equipment, and had Heemaf [nl] / Westinghouse electric motors.

[3] Although the 1,500 V DC system was the most popular of the 1920s, Baldwin-Westinghouse were better known for their AC electric locomotives.

The ESS 3200s, now reclassified as the WH (Werkspoor-Heemaf) 200 class[citation needed][when?]
