The RABe 4/12 of the regional transport Bern-Solothurn (RBS) are three-piece electric low-floor -Gelenkzüge called NExT ( N iederflur- Ex press- T riebzug) by the manufacturer Stadler Rail for the route Solothurn-Bern in Switzerland .
history
After the RBS started operating the first Be 4/8 multiple units in the 1970s and the (A) Be 4/8 at the beginning of the 1990s , in 2007 it was time to purchase a third generation. The new multiple units were necessary both to maintain and to further develop the offer. The new trains RABe 4/12 were intended to increase the steadily growing traffic on the RE line Solothurn – Bern so that the frequency could be increased. When the first six trains were ordered, it was clear that a second series would be procured. However, the planned delivery of the first trains in April 2009 was delayed because an error occurred during the construction of the car bodies during the mechanical processing of the extruded aluminum profiles. Because the deficiency at Stadler was only noticed during a routine inspection during the construction of the 13th box, there was a delay of five weeks. On June 3, 2009, the first three parts of train 21 were delivered, unloaded and assembled in Zollikofen. The first test drives took place on June 5th.
In January 2011, RBS then ordered eight more multiple units from the option. With the additional vehicles, all trains on the RE line Solothurn – Bern are to be run with the modern trains. The ABe 4/12 62-72 will then be comprehensively modernized and then used on the S8 from Bern to Jegenstorf. At the beginning of 2013, the delivery of the 2nd series started; compared to the 1st series, they have monitors instead of light strips for passenger information, more luggage racks, more comfortable seats in 1st class and window panes with better glare and thermal insulation.
technology
The new multiple units represent a further development of the existing trains, but what is new is that all the traction equipment is located in the intermediate car, which has advantages in terms of weight, operational and maintenance. Compared to its predecessors, the train has 20% more traction and a top speed of 120 km / h. For the first time, a multiple unit at RBS is completely continuous, which improves the distribution of passengers. It is also fully air-conditioned and has two wide doors in the third points in each car body. 1st class and a multifunctional compartment are located in the end car on the Bern side.
The drive equipment is a further development of the GTW and Flirt vehicle families as well as equipment for direct current applications such as the Bayerische Zugspitzbahn . This technology is thus already secured through type tests and operational trials. The entire drive equipment is located on the roof of the intermediate car. All driven wheel sets are regulated individually, which enables high tensile forces to be transmitted, even if the rail conditions are poor. Power is supplied by two single-arm pantographs that are placed on the end car. They are connected to the intermediate car via a roof line. With the exception of the roof line, all of the electrical equipment is redundant. The vehicles have multiple controls under themselves and with ABe 4/12 62–72.
Speed record on meter gauge
During the test phase, the first NExT broke the Swiss speed record for meter-gauge trains. The train reached 133.49 km / h between Lohn-Lüterkofen and Bätterkinden . So far this was held by a train of the RhB with 110 km / h. On December 20, 2010, the record in the Vereina tunnel was surpassed by an ABe 8/12 «Allegra» , which reached 145 km / h.
