Among the car numbers 22 to 25 , the associated Albtal Traffic Company (AVG) their four in 1975 Waggon Union (WU) for the light rail Karlsruhe procured Gelenktriebwagen one in their inventory. The serial numbers are 18696 to 18699, the electrical equipment was supplied by the BBC .
Between 1976 and 1991, WU delivered 24 similar vehicles in meter gauge design , including eight two-part six-axle vehicles, in three series to the Darmstadt tram . These were referred to there as ST10 , ST11 and ST12 , but differ in some details from the AVG trolleys. Among other things, they have electrical equipment from AEG .
history
Light rail operation
The expansion of the AVG vehicle fleet became necessary when, on the one hand, the reopened Langensteinbach – Ittersbach section and, on the other hand, the new line to the north-west town went into operation, both of which were served by line A at the time. The small series dealt with here was procured and numbered after the cars 1 to 21 procured between 1958 and 1969 .
In contrast to their predecessors, cars 22 to 25 have a more modern, angular appearance, but were technically compatible with the older vehicles due to their classic contactor switchgear , a development from the 1950s. At the AVG, they were given the same type designation as this one, namely GT8-EP . This abbreviation stood for eight-axle articulated railcar with electro-pneumatic control . In addition, they were capable of multiple traction, both with each other and with cars 1 to 21 .
Another characteristic feature was the lemon-yellow-light green pop paint scheme introduced with the railcars 22-25 . This temporarily earned them the nickname Salad Bowl . Another slang term was bathtub . The reason for this was the elbow rest for the passengers. Similar to the soap shelf in many older bathtubs, this was integrated into the side wall a little below the window. Also new at AVG at that time were the compartment-shaped seating and the upholstered benches with the green and yellow checkered cover.
The four railcars were renamed 122 to 125 in 1982 and remained in use on their three main routes until 1987. These were the Albtalbahn, the Ittersbach branch line and from 1979 also the Hardtbahn . They were then replaced there by the light rail vehicles of the GT6-80C and GT8-80C series.
Tram operation
From 1987 onwards, with the new red and yellow paint scheme, they ran in the Karlsruhe tram network as part of a joint vehicle pool operated by AVG and Verkehrsbetriebe Karlsruhe (VBK) . In terms of bookkeeping, however, they belonged to the AVG until the end and were still permitted on the Albtalbahn and Hardtbahn. Right up to the end, the upholstered seats, the 2 + 2 seating with little standing room, the missing entrance door in the middle section and the luggage rack on the left in the interior reminded of the previous purpose.
Under VBK direction, they were used over the years on lines S2, 1, 5 and 8 as well as the three special tram lines 16, 17 and 18 to the European School . Their retractable folding steps , which were retrofitted in 1991, also allow them to be used largely freely in the entire VBK network.
The two cars 122 and 123 were parked in 2003 due to a lack of demand and from then on served as spare parts donors for their two sister vehicles before they were scrapped in summer 2012. The two remaining vehicles were modernized and in 2001 and 2003, instead of the electropneumatic contactor switchgear, received a modern chopper control and a transistor controller for smooth acceleration and braking as well as for the recovery of braking energy . In addition, the single-arm pantographs received an electric drive, the door mechanism was refurbished and the benches received new covers in the then current staircase pattern. Furthermore, a computer-aided operations control system (RBL) including dynamic passenger information was retrofitted in the interior and a ticket machine was installed. The cars 124 and 125 now carried the modified type designation GT8-70C , with the 70 standing for the maximum speed and the C for the retrofitted chopper control.
The two remaining cars 124 and 125 ran until 2014, together with the classic tram cars of the 142-215 series , mainly on line 5. After they were converted to low-floor cars, car 125 was parked and scrapped in March 2018, while car 124 was still on until 2015 the temporary line 5E operated. Most recently it was used sporadically on the school tram lines.
