WIKIPEDIA defines HIGH SPEED TRAIN like: “A high-speed train is generally defined as one which operates at speeds of over or at 200 km/h (124 mph), with a high level of service, and generally comprising multi-powered elements. Standard locomotive-hauled trains, often able to reach 200 km/h, such as French Corail, European IC trains or Amtrak’s Northeast Regional, unconventional trains, such as maglev and Transrapid, and prototypes are excluded.” (https://en.wikipedia.org/wiki/List_of_high-speed_trains)

We are talking about 300-400 Km/h in the most recent projects. Standard rubber suspensions are not valid for such level of vibration expected in different parts of the trains. SILENTFLEX® Technology solutions are designed to absorb huge quantities of energy, especially at higher frequencies and temperatures, with a expected life of more than 20 years:

  • Raised Floor
  • Table legs
  • Cooling Units
  • Exhaust of Generators
  • Doors closing system
  • Traction Engine Suspension
  • Fan System
  • Restroom
  • etc.

 

CASE STUDY: FRECCIAROSSA 1000

 

he ETR 1000 is the train manufactured  by Hitachi Rail Italy, on behalf of the Italian State Railways designed to reach a top speed of 400 km/h and suitable to operate on the European network. It is a new technological jewel made in Italy able to shorten times and distances.

Not only speed, but also comfort, quality and safety. The ETR 1000 bogie are equipped with solutions that optimize travel quality by offering a level of comfort that, evaluated through mathematical models and test simulations, portends to be by far the highest for the latest generation of High Speed vehicles.

  

SILENTFLEX® Technology installed in the suspended floor is responsible of the maximum comfort for passenger at very high speed during the travel. 10.000.000 Times Compression Test performed during certification confirm more than 30 years of hard job in SILENTFLEX® Floor Suspension system.
