Aiming at the defects that radio communication in the prior art is limited by a communication distance and a channel bandwidth, and a GSM-R (Global System for Mobile Communications for Railways) has the disadvantages of high maintenance cost, long fault handling period, and so on, the utility model provides a railway dispatching order transmission system capable of overcoming the above defects. The railway dispatching order transmission system comprises a vehicle-mounted terminal, a communication server, and a data processing server; wherein, the data processing server is used for compiling a dispatching order and sending the compiled dispatching order to the communication server; the communication server is used for sending the compiled dispatching order to the vehicle-mounted terminal through a GPRS (General Packet Radio Service) or 3G (3rd-Generation) wireless communication network; the vehicle-mounted terminal is used for sending a response to the compiled dispatching order to the communication server through the GPRS or 3G wireless communication network; and the communication server is also used for sending the response received from the vehicle-mounted terminal to the data processing server.
