The Be 4/8 of Aare Seeland mobil (ASM) are three-piece electric low-floor -Gelenkzüge of Triebzugtyps Star ( S chmalspur- T riebzug for a ttraktiven R egionalverkehr) by the manufacturer Stadler Rail for the routes Solothurn Niederbipp , Langenthal-Niederbipp-Oensingen and Langenthal – St. Urban in Switzerland .

history

In order to replace the existing 40-year-old rolling stock and ensure the extension to Oensingen planned at the time , the ASm ordered three 39 meter long Be 4/8 multiple units together with two additional GTW Be 2/6 for the Biel – Täuffelen – Ins route . Because the GTW did not meet the requirements due to the narrow curves with a 35 meter radius, either an existing basic construction ( TB Be 4/8 , Spatz or its predecessor) had to be adapted or a new concept developed. Stadler decided on the second variant for strategic reasons in particular and designed the Star.

technology

The Be 4/8 replaced the old rolling stock (right) of the " Bipperlisi ".

The star's concept was derived from the standard-gauge Stadler Flirt . The multiple units consist of two low-floor power cars at the ends that are attached to the non-powered intermediate car. As with the Flirt, the electrical and pneumatic equipment is located on the roof and directly behind the driver's cab above the motor bogie . On Jacobs bogie like flirting because it no low-floor car transitions are possible with meter gauge vehicles has been omitted. The vehicles meet the requirements of both rail and tram vehicles . The car body is welded from extruded aluminum profiles and screwed to one part. Due to the required for railway vehicles chest compression force of 800  kN and the tight curves had a new box hinge are developed, because joints from the tram area are only designed for a longitudinal compressive force of 400 kN.

The Star is characterized by a high level of performance and acceleration as well as large low-floor areas in the passenger compartment. Two redundant motor bogies at the ends allow a drive to continue if a drive train fails. Up to three multiple units can run in multiple control . Air conditioning, air-sprung motor and trailer bogies and a passenger information system serve the comfort of passengers and drivers.

The vehicle concept of the Star served as a model for the ABe 4/8 Diamant of BDWM Transport .
