The site, which owns one of the three six-coupled tanks in this batch, explains that this was a standard short-haul design by Hohenzollern. Altogether 69 were produced from 1914, including 6 for the Argentine broad gauge. One of the most powerful of six-coupled tanks on the standard gauge, the design still owned an adequate factor of adhesion as well as a reasonably large boiler and grate.
The locomotive owned by the site was the middle engine in this batch (works #4267-4269) delivered to BASF in Dusseldorf. It operated on BASF property until 1959, when it was sold to a Rhenish brown coal company in Neurath.
Out of service in 1971, the locomotive began a long journey to Switzlerland in 1973. Beginning in 1981, after he purchased the engine, Urs Rueesch restored this locomotive to service over the next 5 years. It operated on tourist lines over the next 16 years until on 27 April 202, Rueesch donated to the VEREIN ZUR ERHALTUNG DER DAMPFLOK MUNI (Association for the Preservation of the MUNI steam locomotive), of which he was president. It remained in operation in 2005.
