[0002] A locomotive is a self-propelled vehicle that pulls or pushes railway vehicles without carrying a commercial load; it is commonly known as a train engine. In terms of fuel consumption per ton-kilometer, locomotives are the most energy-efficient land transport vehicle. Railway locomotives are equipped with radios to receive advance information about their movement or stopping.

[0003] The existing ground radio is just a single unit without a matching handheld communication device (walkie-talkie or handheld step-by-step phone). Therefore, it lacks a charging structure for charging the handheld communication device and an adapter structure for audio conversion with the handheld communication device. This results in certain limitations in the actual use of the existing ground radio. In addition, if a handheld communication device is used, a separate charger is required, which will occupy the effective space on the locomotive's platform.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a ground radio based on railway locomotives to overcome the shortcomings in current practical applications. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model embodiment is to provide a railway locomotive-based radio base unit to solve the problems in the background technology mentioned above.
