Compatibility rolling stock – track circuits: Test Campaigns and Results (Paris 21.4.2009) 2

emkamatik Test campaigns

Tests in different countries:

• Germany: ICE-S (test train for Railcom)

• Switzerland: Re 460 (scheduled IC train)

• France: TGV DASYE (test train for Railcom)

• Italy: Several trains (test trains for Railcom)

• Czech Rep. / Poland: CD 163 (scheduled trains)

Total more than 10‘000 km of test runs
