The Re 6/6 , according to the new designation system Re 620 , are six-axle, electric locomotives of the Swiss Federal Railways (SBB), which were purchased to replace the Ae 6/6 in heavy duty on the Gotthard.
Construction and technology
The requirements for the series resulted in the need for six drive axles for traction. In order to still achieve good cornering properties with low wear, in contrast to the Ae 6/6 three two-axle bogies were installed, whereby the middle one can move a lot sideways. For better cornering of the two following bogies, elastic cross couplings were also arranged between the three bogies. The cross coupling is based on the principle that was originally developed for the Ge 6/6 II of the Rhaetian Railway (RhB). Two of the four prototypes received as the Ge 6/6 II RhB a split locomotive body, wherein the joint is analogous to RhB Ge 6/6 II can only move vertically in order to fit slope changes.
The softer secondary suspension of the middle bogie chosen for the other two prototypes has proven itself in trial operation, so that the one-piece box was used in series production. The two prototypes with a split box will continue to be used in regular operation.
The design is based on the shape of the Re 4/4 II , as is the operation and conventional transformer technology, which was last used on the Re 6/6. In the Re 6/6, however, there are two transformers (power transformer and regulating transformer) which are located in the locomotive box between the bogies.
The front section, although similar, has a higher roof than the Re 4/4 II / III . That is why the Re 6/6 is said to have a “high forehead” that distinguishes it from the Re 4/4 II / III from a distance, even from the front .
As with the Re 4/4 II / III , it is planned to equip all locomotives with a cab air conditioning system. The first machines will be converted from the end of 2005. In contrast to the Re 4/4 II / III, this will only be recognizable on one side of the box on a door without ventilation slots. The rest of the changes, such as replacing the lowered windows, etc., are only visible up close.
business
The Re 6/6 - originally assigned to the Gotthard locomotives - have multiple controls together with Re 4/4 II , Re 4/4 III , Re 4/4 IV and RBe 4/4 . In passenger transport, they pull heavy passenger trains over the Gotthard (as an alternative to a double traction of two Re 4/4 II ). In freight transport, they are used nationwide for heavy freight trains, on the Gotthard route very often in multiple control with a Re 4/4 II or Re 4/4 III . Such a tandem, often referred to as " Re 10/10 " for short (due to the 10 driven axles), is able to carry the increased draw hook load (towing mass) of 1400 tons over the 26 per mil gradient of the Gotthard route. The permitted tow hook load is actually only 1300 tonnes at 26 per thousand and was also valid for the Gotthard and Lötschberg transit axes for a long time, which explains the different information in the literature. For heavier trains (up to 1700 tons are operationally possible, for a long time this value was only 1600 tons), a push locomotive must be used in order not to overload the tow hook, whereby a push locomotive may push a maximum of 300 tons (permissible tow hook load + 300 tons = total trailer mass ).
In 1990 locomotive 11638 was scrapped and broken off due to an accident. In 1992, only the remaining locomotives were taken into account for the change to the UIC-compliant number grid, which meant that 11638 no longer received a UIC number. The effective redrawing with UIC numbers, however, was never tackled consistently. In the course of 2005 the UIC numbering scheme was revised, whereby the 620 001 (instead of 000) was set as the smallest company number and, for the sake of simplicity, the no longer existing 11638 was subsequently given the number 620 038. At the beginning of 2006 almost half a dozen machines had the new name.
When SBB was divisionalized on September 1, 1999, the first thirteen locomotives 11601–13 were used for passenger services, but were exchanged for Re 460 on January 1, 2003. So today all 88 remaining machines belong to SBB Cargo . Due to the reallocation of the Re 460 to the Passenger Traffic Division , the Re 6/6 dominate the freight traffic on the Gotthard route again today, alongside the newly acquired Re 482 .
After two locomotives were given a trial radio remote control for the pushing service with locomotives of the Re 460 series at the end of the train at the Gotthard, around 30 locomotives were equipped with it from 2000. In order to make them administratively recognizable, they were given the designation Ref 6/6 . The remote controls were dismantled as early as 2003, since when all Re 460 were handed over to passenger transport, there were no longer any remote-controllable locomotives.
The locomotives were assigned to the Erstfeld, Bellinzona and Lausanne depots until around 2002, after which they were no longer assigned to a depot. Deadline work is carried out at the service locations in Basel and in the Limmattal marshalling yard. The Bellinzona industrial plant is responsible for revision work.
Sections of the Gotthard route and the Lötschberg base tunnel have been equipped with train protection according to the ETCS Level 2 standard and GSM-R radio since 2007 . That is why 60 locomotives were converted accordingly by Stadler Rail . The remaining locomotives received EuroZUB and GSM-R radio.
In August 2018, the prototypes 11603 and 11604 were sold by SBB to the company RailAdventure , which specializes in transfer and test drives . The 11603, originally christened Wädenswil, was renamed Suisse Svizzera.
In autumn 2019 it became known that the prototypes 11601 and 11602 had been sold to a private person in the vicinity of the Swisstrain association. It is planned that the 11601 will be overhauled and made roadworthy again, the 11602 will be used as a spare parts dispenser. The 11601 was therefore transferred from Bellinzona to Sissach on October 20, 2019.

Accidents
- On February 16, 1990, the Milan-Paris Eurocity, pulled by the 11638 locomotive, collided with an SBB construction train at Saxon station . Since the impact was very violent at 140 km / h, three people were killed in the accident and 12 others were injured.
- On August 8, 2011, the Re 6/6 11666 collided with an NPZ shuttle train at the Döttingen AG train station . The locomotive was severely damaged, but unlike the control car of the NPZ, it did not derail. Eight people were injured in the accident.
- On October 23, 2014, at 7:03 a.m., a collision occurred between the two SBB Cargo Re 6/6 locomotives 11620 and 11640 during a shunting movement in the St. Maurice station , causing considerable damage to the vehicles. As it turned out later, the damage to the 11620 was so great that it was no longer worth repairing. It was demolished on February 10, 2017. The 11640 has been in operation again since April 2016.
- On May 13, 2015, shortly after midnight, two freight trains collided from the side at Erstfeld station . A freight train from SBB Cargo International, led by Re 6/6 11673 “Cham” and Re 4/4 II 11333, left the Erstfeld station on May 13, 2015, at 00:03 a.m. when traveling to the side in a sideways direction crashed into a BLS Cargo freight train. The two BLS cargo locomotives Re 485 008 and Re 486 509 remained undamaged. The two trains were heading in the same direction. The course of the accident and the cause are investigated by the Federal Security Investigation Board (SUST). The 11673 was demolished on July 15, 2016.
