The GT5 (abbreviation for " Articulated multiple unit five-axle") is a tram - articulated multiple unit with five axles, which was manufactured by MAN in 1964 (car 522-534) and 1968/69 (car 511-521 and 535-552) for the Augsburg tram was built. Since only the then Stadtwerke Augsburg ordered this type of vehicle, it is considered characteristic of the Augsburg tram.
Procurement and remodeling
As a successor to the eleven large-capacity trains of the M series from Rathgeber used in Augsburg , the Augsburg transport company initially commissioned MAN in Nuremberg to manufacture 13 articulated multiple units. These were put into service in 1964 with the car numbers 522 to 534. The articulated railcars were designed in such a way that they can be quickly and easily separated into two halves. Only in this way was maintenance possible in the small workshop in the depot at the time. As a result of the positive experience, seven more vehicles (wagon numbers 535 to 541) were ordered from MAN in 1968.
In order to maintain a uniform fleet of vehicles, the municipal utilities decided to convert the eleven large-capacity trains of the M series (car numbers 263 to 273), which were also supplied by MAN in 1956, into GT5s using new components. This happened partly at MAN and partly in our own workshop. In this way, the new cars 511 to 521 were created from the old railcars of the large capacity trains and the cars 542 to 552 were made from the old sidecars. As a result, a total of 42 articulated railcars of the GT5 type were available in 1969.
In 1972/73, adjustments to the GT5 had to be made in the course of the introduction of the conductorless one-man operation. The conductors' seats were removed and validators , contact steps, anti-trap protection, light barriers and push buttons for opening the doors from inside and outside were retrofitted. The first door was an exception. This should continue to be operated and monitored by the driver. In addition to the changes mentioned, the seating was also rebuilt, a stop tape announcement was installed and the flow of passengers was stopped .
A few years later (from around 1979/80) the plug-in signs on the front of the vehicle that had been customary up to that point were replaced by automatic brooches for marking lines and destinations. In addition, a computer-controlled operations control system was installed . The color scheme was also changed from beige with green decorative stripes to white-emerald green with black battering rams and red-green decorative stripes.
Technology and equipment
The one-way vehicle consists of a welded steel construction and consists of a powered three-axle front carriage with a steering three-axle frame and a non-powered trailer with a two-axle running bogie . The two car parts are connected by a rubber-sprung coupling joint and sealed with concertina-like rubber bellows .
The drive of the outer axles of the three-axle steering frame is carried out by two Siemens pillar bearing motors . These motors are controlled by a manually operated, multi-stage cam travel switch with switching aid. The manufacturer of the steering and bogies was Klöckner-Humboldt-Deutz .
The brake system consists of an electric service brake , which is supplemented by a compressed air brake . The function of the parking brake is taken over by a spring-loaded brake and an electromagnetic rail brake .
Whereabouts
After this type of vehicle shaped the cityscape of Augsburg for many years, it was finally retired in 2000. The scrapping of older cars had already begun in the mid-1980s, but it was only with the delivery of the Combino tram that the municipal utilities were able to do without the GT5 completely. The still operational vehicles were sold to the Iași tram to Romania in 2001 (car 511, 522-525, 531-536, 538, 542, 544 and 545). Only car 535 could be used by the association “Friends of Augsburger Straßenbahn e. V. “thanks to a donation from the SPD Augsburg for 1000 DM from the municipal utilities. Today (as of 2016) it is parked in the vehicle hall of the association.
All GT5s delivered to Romania were withdrawn from regular operation in July 2010. The vehicles were then parked in the Dacia depot. In 2013 the wagons were scrapped. Currently (as of 2016) there is only one GT5 (ex Augsburg 545; Iași car number 354) as a museum car in Romania.
