PStB 3 II to 5 II and 8 to 10 is the designation for two-axle tram locomotives for the meter-gauge Plettenberg tram .
history
The Plettenberger Tram (P.St.B.), which has existed since 1896 - from 1942 Plettenberger Kleinbahn - served routes in the Sauerland that were mainly in the street area. Therefore, she mainly used tram locomotives. The advantage of these locomotives was that the width of the train could be seen from the front, and they were also intended to reduce the risk of shy horses. In 1913, a superheated steam locomotive was procured for the first time from Henschel in Kassel , the first superheated steam tram locomotive in Germany, it received the number 5 in a second occupation. It proved itself well, the tractive power compared to the existing locomotives was more than 50% higher, with lower consumption at the same time. The other locomotive purchases were also superheated steam locomotives from Henschel, despite the higher maintenance costs. In 1919, 1924 and 1925 three locomotives were procured and classified as numbers 8 to 10, the numbers 8 and 9 were also given the names W. SEISSENSCHMIDT and PLETTENBERG of already decommissioned locomotives. At 2550 mm, they were slightly wider than the 2300 mm of the 5 II locomotive , so that in addition to the narrow-gauge coupling, there was also space for a laterally offset standard-gauge coupling with buffers. This was necessary for moving standard gauge wagons in the three-rail track of the Eiringhausen (Plettenberg Staatsbahn) and Plettenberg Oberstadt stations. Due to the wider locomotive body, the coal box at the rear end of the locomotive 5 II could also be omitted.
In 1927 two more locomotives were procured, with a slightly higher weight and higher steam pressure (13 bar); they were given the numbers 3 and 4, each with a second crew. These were the penultimate tram locomotives that were built in Europe, such locomotives were considered obsolete. All locomotives were equipped with brakes according to their intended use, so until recently the locomotive 5 II had no indirect brake and could only be used in freight train service. The wide open driver's cab and the workplace next to the boiler were very stressful for the staff. Locomotive 10 was retired in 1960, Locomotive 5 II in 1961, Locomotives 8 and 9 then in 1962. Locomotive 4 II was initially kept for museum use, but was scrapped in 1964.
Locomotive 3 II was last in reserve for the diesel locomotive procured in 1959. Most recently, it was used to move standard gauge wagons in Eiringhausen. The deadlines expired in 1967, and in 1968 the locomotive was sold to the German Railway Association .
Locomotive Plettenberg
Locomotive 3 II arrived in Bruchhausen-Vilsen in 1971 and was named PLETTENBERG. After several attempts, the boiler work could begin in 1988, and it was restarted in 1991. Since then it has been used on the museum railroad. The standard gauge buffer and coupling has not been restored, but the balancing lever coupling has been reattached.
technical features
The locomotives were superheated steam locomotives with a Schmidt small-tube superheater with a heating surface of only 11.5 m². The long boiler had only one shot, the firebox was made of copper. The water was supplied via two suction Strube injectors. Two sand containers sat on the kettle.
The construction as a box locomotive meant that the engine driver stood at the side of the boiler, so the fittings are attached to the side of the boiler. To protect the engine driver and stoker there were sliding windows on the otherwise open upper half of the side wall. There was no engine cowling.
The locomotives had Heusinger controls with piston valves. The drive took place on the second axis. The water tank was housed in a metal frame, and there were two boxes on the right and left in the back. Coals lay behind the kettle.
Except for the 5 II , the locomotives initially had a Körting suction air brake. Locomotives 8 to 10 as well as 3 II and 4 II were later converted to a compressed air brake, and they received air tanks on the roof. When delivered, the locomotives had a balancing lever coupling with a rectangular slot buffer, as the trolleys were coupled with a coupling rod and bolt in the slot buffer. Except for the 5 II , they also had lateral buffers. In the narrow curves of the routes it was easier to couple the narrow-gauge wagons with a short coupling rod, so the balance lever coupling was superfluous and was removed. In addition, the locomotives had a Latowski steam flare.
