To strengthen the management of dedicated lines and dedicated railway cargo transportation, and further improve the management level of dedicated lines and the quality of freight services. The special line handover system developed by our company automatically identifies the vehicle number of vehicles entering and leaving the special line, saves the vehicle image data, and transmits the machine inspection information into the freight station system, which provides the basis for the handover of road enterprises and generates truck transfer orders, avoiding the opinions and disagreements between road enterprises and trucks on the delayed occupation fee. The electronic ledger of the dedicated line can be queried, while wireless handhelds are used for data tracking and timely processing of vehicles in and out.
