Railway dynamics

The technical specification for interoperability concerning the trans-European high-speed infrastructure subsystem applies to all European high-speed railways. Thereby, the requirements of several Eurocodes for train/track dynamic interaction, train runability and cross-wind effects will apply

High-speed trains

High-speed trains require state of the art calculation procedures with respect to train runability, safety and passenger comfort. COWI uses in-house expertise and experience to perform such state of the art calculations needed for projects like the Øresund Bridge and the planned Qatar-Bahrain causeway and the Messina Strait Bridge, Italy.

Eurocodes

COWI refers the most recent version of Eurocode in order to use the most up to date regulations in a given area. COWI is also adapting to local codes and regulations if local codes specify other regulations than what is specified in Eurocode.

IBDAS

Using the highly versatile and proven in-house program IBDAS, COWI can produce quick and precise results regarding rail/train/bridge interaction under different load cases by using a specially developed train model with multiple degrees of freedom per coach. The model setup can also take turbulent cross-wind interaction into account.
