G 3/3 is a steam locomotive series of the Waldenburgerbahn (WB) with a 3/3 wheel arrangement. A total of five locomotives from this series were delivered to the WB.
The locomotive with the WB road number 3 was delivered in 1882 by Krauss & Co in Munich (factory number 1049) and the locomotive with the WB road number 4 in 1887 by the SLM in Winterthur (factory number 458).
The other locomotives were three identical machines with the WB company numbers 4 ", 5 and 6. These were again delivered by the SLM (factory numbers 2094, 1440 and 2276).
history
The locomotive, delivered on April 6, 1887, was put into service under the road number 4 and the name of the district capital Waldenburg . Unfortunately, this machine did not prove itself. In addition to the normal overhauls, there were always major, costly repairs to be done. During the last revision in 1908, the bedding of the boiler pipes in the fire box pipe wall was criticized. So it was decided to retire the WB Lok 4 in 1909. The demolition took place in 1910.
The first locomotive in the series was delivered on August 26, 1902. It was given the operating number 5 and the name of the co-founder of the Waldenburgerbahn " Gédéon Thommen ". The second followed on February 23, 1910. Since this locomotive was purchased as a replacement for the number 4 (1887), which had already been taken out of service, it was assigned the number 4 that had become vacant. It was named " Langenbruck ". On September 23, 1912, the third locomotive, No. 6, went into service. It was given the name " Waldenburg ". On October 19, 1933, the “G. Thommen ”had a broken axle and after that it no longer achieved the quality it had before. In 1953 the Waldenburgerbahn was electrified and the steam locomotives were taken out of service. The no. 4 "Langenbruck" was scrapped. Locomotive no. 6 "Waldenburg" was saved from the same fate thanks to the association "Eisenbahn- und Modellbaufreunde Luzern" (EMBL). The locomotive was sold on behalf of the members of the "Schweizerischer Verband Eisenbahn -Amateur “(SVEA) and - after the exterior renovation by the EMBL - given to the newly opened Swiss Museum of Transport (VHS) in October 1958 .
The locomotive No. 5 "G. Thommen “was initially drawn (discontinued) in a locomotive shed in Waldenburg. In 1961, the municipality of Liestal showed interest in erecting the locomotive as a memorial in the Liestal station area. This request was granted. No. 5 stood in the open air, not spared from wind, weather and vandalism, until it was put back on the Waldenburgerbahn on June 30, 1975 and towed to Waldenburg. Volunteers there have completely restored the locomotive. In time for the railroad anniversary “100 years of Waldenburgerbahn”, the “G. Thommen ”with restored rolling stock from the“ Wilhelminian era ”. It has been in service as a historic locomotive since 1980 and is looked after by the steam group of the WB. On September 23, 2018, it ran for the last time on the Waldenburger Bahn, as it loses its original area of application due to the gauge change of its distance to 1000 millimeters .
Technical
The middle axle of the locomotives is designed as a drive axle. From here, the drive force is transmitted to the 1st and 3rd axes by means of coupling rods. On the boiler there is a steam dome behind the chimney and behind it a regulator dome. This is where the controller is located, which is operated from the driver's cab via a lever mechanism. The safety valve is located on the steam dome. The locomotives are equipped with a spindle brake, a counter pressure brake (acting on the locomotive) and an automatic vacuum brake (Hardy system), which acts on each individual car of the attached train.
