In this paper, we characterize the channel for fifth-generation (5G) millimeter-wave (mmWave) railway communications. In order to involve the railway features in the channel models, we realize extensive ray-tracing simulations in the 60 GHz band with 8 GHz bandwidth in realistic mmWave railway scenarios. The four angular spreads - azimuth angular spread of arrival (ASA) and departure (ASD), elevation angular spread of arrival (ESA) and departure (ESD) - are extracted and analyzed in detail. This angular domain information together with our previous work on path loss exponent, shadow factor, Ricean K-factor, and root-mean-square (RMS) delay spread, characterize the 5G mmWave railway channel comprehensively. The two parameter tables can be input into the standard channel models.
