Yes, that train makes a difference. Windows are tinted slightly using a metallic layer in the middle of the laminated glass, and that metal acts as a Faraday barrier. It depends entirely upon the glass and the train makers choices. Its a well known issue in the rail industry and just one of many reasons which high speed data will not be available on the deep tube sections of London Underground.
