The cornering speeds for trains in train

The upper speed information on the rectangular

train row R. The information on the round board
is for trains in train row D. It is
used to protect certain steel bridges of older

the speed
of train row A applies to the corresponding trains .
The city ​​express trains were run by the Re 4/4 I in the 1940s and 1950s and ran according to series R. Historical train with Re 4/4 I, light steel wagons and a standard wagon I at Chillon Castle .

In Switzerland and Spain, train rows , together with the brake row, define the maximum speed and the cornering speed of a train. The series of trains depends on the composition of the train and is indicated with a capital letter.

Switzerland

history

Switzerland is a country with an extremely large number of narrow curves. In order to shorten travel times, they started to increase cornering speeds early on. In 1946, the R train series was introduced with cornering speeds increased by 5 km / h. The railcars RFe 4/4 , the locomotives Re 4/4 I with 14 tons axle load and later the railcars RBe 4/4 were allowed .

Thanks to side-sprung axles and cross-coupled bogies , heavy locomotives such as the Re 4/4 II could later be approved for the R series of trains. Their prototypes were initially put into operation under the name Bo'Bo '. Only on the basis of the measurements made on the vehicles was the train series R granted and the locomotives finally designated as Re 4/4 II.

Although the standard wagons III were prepared for the installation of the tilting technology , the SBB decided not to drive with the arching speed for economic reasons . A few attempts remained, which showed that traveling time savings of around 15 minutes would have been possible on the Zurich - Geneva route . It was not until two decades later that the scheduled tilting trains started operating in Switzerland. For the flies to Milan trains running Cisalpino trains ETR 470 the Zugreihe N was introduced.

Rows of trains on standard-gauge railways

  • Since the withdrawal of the Ae 6/6 from the passenger all drive trains on the SBB - and BLS -Netz after Zugreihe R . In the case of locomotives, the R is usually included in the designation . But there are also freight wagons that are allowed to run after the R train series. The maximum speed of train row R is 160 km / h or 250 km / h, depending on the brake row.
  • The Zugreihe A is today usually at freight trains used. Trains in series A are allowed to run at a maximum speed of 120 km / h.
  • With the Zugreihe D goods trains with an axle load of more than 20 up to 22.5 tons. These wagons may only run on routes that are approved for route class D. In the train service regulations , a maximum speed of 100 km / h applies to train series D.
  • For the tilting trains RABDe 500 , ETR 470 and ETR 610 , with which higher cornering speeds than the train row R can be driven on selected routes, the train row N is determined. Tilting trains have a reduced axle load of a maximum of 16 tons so that the permitted track displacement forces are not exceeded .
  • On the Südnetz the Südostbahn comes Zugreihe O used. It differs from the train series R in the lower switching speed of the R brake . This results in shorter braking distances on steep sections with an incline of 50 ‰, which allows a higher driving speed of 60 km / h.

With the commissioning of the double-decker intercity trains , which are equipped with roll compensation , a new series of trains W will be introduced. The roll compensation prevents the car body from tilting outwards in curves and thus enables increased cornering speeds. The speed of train series W will be between that of train series R and N.

Rhaetian Railway

The Rhaetian Railway operates trains in which all cars have a maximum axle load of 10 tons - this includes all passenger cars - according to train series R. Train series A is for trains with axle loads of over 10 tons and train series D for trains with axle loads of 12.6 to 16 Tons determined. The speed of train row D is limited to 60 km / h. The D series of trains is not used on the Chur - Arosa route and the Bernina Railway, as the axle load there is limited to 12.5 tonnes.

Spain

The train series in Spain start with the train series "N" for normal trains, which means driving on the route with a lateral acceleration of 0.65 m / s². There are then successively further, alphabetically arranged intermediate steps of arc-fast driving up to class "D" with a permissible lateral acceleration of 1.8 m / s². This roughly corresponds to the Swiss "N" series.
