These are old photographs I found in the Perumka archive, click on the images to get a more detailed look.

Hollandsche Maatschappij tot het maken van Werken in Gewapend Beton Weltevreden.

Hollandsche company producer of reinforced concrete Weltevreden (a suburb to the South of then Batavia - now Gambir area of Jakarta)

A Staats Spoorwegen switcher coupled to a PKR depressed flat car carrying a prefab concrete storage tank somewhere in Jakarta

The Staats Spoorwegen were flourishing, they moved more and more tonage on their network in Java, and some of the routes were quite mountainous with grades of 1 in 25 and curves down to 150 meter (450 ft) radius. So when the normal engines where found to be inadequate they ordered Mallet semi articulateds. Here a pair of the latter batch of 2-6-6-0T mallets (built by Werkspoor of Amsterdam) with a train pausing on the bridge.

I am not familiar with the bridge so I can't say where. (anybody knows? e-mail me)

Now for something different:

A steam powered crane built by Figee of the Netherland.

Another steam crane being used to hoist a cage with a tiger inside. This picture was taken on the privately owned Madoera Stoomtram Maatschapij (Madura steam tram company) on the island of Madura just around the eastern corner of Java
