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).

The ESS 3200s were first used on 6 April 1925, which also was the same day the first electrified railway line in Java from Tanjung Priok to Meester Cornelis (modern day Jatinegara) was opened.^[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.^[2] Six locomotives were built for the line.^[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?]} were in service until 1976.

After sitting idle for many years, 3202 was returned to working order. It was returned to service and as of 2013, was hauling tourist trains in Jakarta.^[3] 3202 currently bears road number 3201. The original 3201 was totalled in the 1968 Ratujaya train collision [id].^[4]

3202 is currently stored at Manggarai rolling stock workshop.
