The mobile cellular service coverage of nomadic users in the context of high speed vehicular scenarios, e.g., railroad trains, is challenging. Energy saving efforts of the past years have lead to substantially increased vehicle penetration losses, e.g., by metal shielded windows. As a result providing coverage into railroad cars is an emerging topic for optimization efforts, either based on network deployment or on railroad car materials. The quality of these efforts rely heavily on the understanding of the vehicle penetration loss and its angular dependency. In this paper we present a distributed measurement methodology and setup allowing for measuring the penetration loss of railroad cars. We validate the feasibility of the methodology in a real world measurement campaign in Austria. There, we compare two different car configurations, standard and prototypical, at 800-2600MHz for azimuthal angles of arrival of 0-60degree. The comparison of the two configurations shows a substantial lower penetration loss of the prototypical setup due to windows with alternative material treatment.
