The standard gauge tank locomotives of the Hohenzollern type Crefeld were a three-axle industrial railway type produced in large numbers by the manufacturer Hohenzollern . They were preferably sold to mining companies such as the Hibernia colliery .
Some were in use until the mid-1970s, one at the Eschweiler Mining Association even until 1985. Four locomotives have been preserved at clubs.
history
The type was derived from the Prussian T 3 , whereby the frame and the drive were more powerful. A total of 178 copies were built between 1895 and 1915, which were divided into the three categories Crefeld , Crefeld a and Crefeld b . The categories differ in terms of dimensions and technical data.
The locomotives became dispensable from the 1960s when collieries were closed or replaced by diesel locomotives . Most were retired by the late 1960s.
construction
The locomotives worked according to the wet steam process and were very similar in appearance and technical details to the Prussian T 3 . The steam engine had flat slide valves that were inclined forward. The Crefeld type had Heusinger controls . The middle axis served as the driving axis, which could be sanded from the front and rear through a sand downpipe. The sandpit was mounted on the top of the boiler and made cuboid.
The frame and drive were sturdy. The water tank was housed between the frame cheeks under the boiler, and the right side box was used for the water supply. This gave the locomotive the capacity of 4 m³. The water inlet was in front of the box on the side. The left side box contained the coal and could be emptied from the driver's cab.
The machines that are kept running are equipped with an indirect brake . All wheels were braked from the front, they were sprung with leaf springs , which were arranged around the circumference of the first two wheels and under the axle bearing on the rear axle. The springs on the first and middle axles were connected to each other by compensating levers. Further equipment included electrical lighting, a Ramsbotton type safety valve , signal whistle and bell.
Preserved locomotives
Hibernia 7-C
This locomotive with the serial number 1962 was delivered to the Hibernia colliery in 1906 and was called the Hibernia 7-C . It stayed there until 1956 and then drove for the Radbod colliery in Hamm as Radbod 3 for a few years . Until 1974 it was based at Ruhrkohle AG and designated as D-712 .
In 1974 it was taken over by the Weserbergland Steam Railway (DEW) to transport museum trains there. In 1978 a derailment forced the locomotive to be shut down. After repairing the damaged engine and the boiler, it was put back into operation. The machine could only move trains up to 120 tons on the DEW routes and therefore only pull a maximum of four cars.
Since 1985 the locomotive has been under its former name Radbod 3 at the Hamm Museumseisenbahn , where it was still operational in 2015, and will be parked in 2020.
Mining company Hermann Bork 1
This locomotive with the serial number 2227 was sold to the mining company Hermann Bork in Lüdinghausen , wore the number 1 and ran until 1928. After that, it came to the Eschweiler Bergwerks-Verein and was used in shunting at various collieries around Aachen . It was in operation until 1985, making it the longest in service in the series. In 1985, the locomotive was donated to the Association des Musée et Tourisme Ferroviaires in Luxembourg , where it has been in service with its last name Anna 9 ever since . As of 2016, their preservation could be seen as guaranteed.
