Results from the European 5th Framework project 'InfraStar' are presented. The InfraStar project is developing a two-material rail to increase the productivity and reliability of rail infrastructure. The two-material rail aims to be rolling contact fatigue (RCF) resistant and to reduce squeal noise. The InfraStar consortium has built a high level of wheel-rail expertise and understanding regarding RCF initiation and development, level and position of wheel-rail contact forces, and new interface materials and has gained experience in both laboratory and field test operating conditions.Within the project a validated theoretical train-track interaction model and a fatigue design model for two-material rails have been developed. This paper focuses on the field test results of the two-material rail, and how the predictions and expectations from the selection process match with the results observed in track. Results are very promising. The two-material rail prototypes, now over 1 year in track, show no RCF damage where the non-treated rail shows clear RCF damage. The development of the application process and other objectives of the InfraStar project are discussed.
