T16903 – SBB Class Re 482 Electric Locomotive
Bombardier is offering its TRAXX platform that has been reworked several times as a "jack-of-all-trades". Due to the lower maximum speed of 160 km/h / 100 mph, all of the TRAXX electric locomotives run with the more affordable axle-suspended drive system with built-in three-phase asynchronous motors. The control of the wheel sets in a truck is done or provided in common by means of current converters. The longitudinal forces between the truck and the locomotive body are transmitted by means of low-linked draw and pressure bars. There has been another reworked TRAXX version since 2005 with an altered, crash-improved locomotive body. The TRAXX locomotives are designed for all power systems and the train safety technology can also be adapted at any time for different railroads.
In 2001, Bombardier in Kassel was given a contract from the Swiss Federal Railways (SBB) to deliver ten dual system freight locomotives analog to the DB class 185 to the SBB Cargo business unit. Included was an option for 40 additional units that was also executed at once. Starting in the summer of 2002 the first units went into operation as the class Re 482 – beginning with road number 482 000. After the conversion to the TRAXX-2 platform in 2005, SBB Cargo had to be satisfied with the last 15 units (482 035-049) in this TRAXX version. In a departure from the DB class 185 units, the Re 482 units have four pantographs, two each for the German, and 2 each for the Swiss catenary. The Swiss safety systems Signum and ZUB 262 are installed in addition to the German systems Indusi, LZB 80, and PZB 90. Furthermore, cameras are used in place of rear view mirrors on the locomotive body.
These locomotives are used primarily on the international North-South axis of Germany – Switzerland, but they are also leased sometimes to other transportation firms. In anticipation of the opening of the Gotthard Base Tunnel (57 km / 35.63 miles) on December 11, 2016 SBB Cargo presented the first of nine locomotives in the new "Alpäzähmer" look on August 18, 2015. The protected name brand consists of the noun "Alpen" / "Alps" and the verb "zähmen" / "tame". SBB Cargo is thereby showing as the leading Swiss rail transport firm on the North-South Axis the conquest of the Alps as an obstacle for freight service by using the base tunnel.
