The 5th generation mobile communication system (5G), provided by mobile network operators (MNOs), is expected to dramatically improve three characteristics, namely, "enhanced Mobile Broadband (eMBB)," "Ultra-Reliable and Low Latency Communications (URLLC)," and "massive Machine Type Communication (mMTC)," compared to conventional mobile communication systems. The introduction of 5G services in railways is expected to lead to the introduction of new applications that could not be realized with conventional ground-to-train communication systems. Therefore, this paper outlines our current research on the introduction of public 5G services provided by MNOs to railway operations and the results obtained so far.
