Data from L Derens"The Dutch Rhenish Railway and Its Locomotives"," The Locomotive Magazine, Volume XXVI [26] (15 June 1920), pp. 137-138. 1-7 in 1879, 8-12 in 1880, and 13-17 in 1881.
As the Rhenish continued to expand its network during the 1860s and upgraded its train control by adding block-signals and detonating fog signals in 1869, the railway began builidng steam tramways for local traffic. One connected Hague with Scheveningen over 4.715 km (2.9 miles) and was opened on 1 July 1870. The Ceinture connected Rhenish's Amsterdam station at Weesperpoort with Holland Railway's Central Station (opened 4 August 1880) over 5.1 km (3.2 miles) of tramway. This stubby little tram motor had a short horizontal boiler in its coach body; a slide valve regulator was housed in a small dome. Its running gear wore shrouds to protect pedestrians from its running gear. No 1 offered a slightly larger grate (4.47 sq ft/0.415 sq m) and slight differences in heating surface area. 13-17's heating surface area totalled 142.1 sq ft (13.2 sq m). Those operating on the Hague line were required to divert their exhaust steam through a slide valve into the rooftop water tank where a water-ejector placed in the water tank condensed it for reuse. Similar noise-reduction diversions of the safety-valve and vacuum ejector steam sought to render the tram motors more acceptable to the city. An unusually long-lived class as tram motors went, the class was updated with continuous brakes in 1902-1903.
