Research conclusions：(1)Wuyuan station designs two respective interlocking systems for the two yards，and the intersecting cross-over turnout is controlled by the interlocking system of the yard I．The route between two yards is set up by some sectional routes．(2)The signal indication turns on when the train runs from the yard 11 to the yard I，while the signal indication turns off when the train runs from the yard I to the yardⅡ．(3)Due to the automatic transition mode of every home signal，the CTCS-3／2 grade transition point does not need to be set up，when the EMU runs from the Jiujiang-Jingdezhen-Quzhou Railway to the Hefei-Fuzhou Passenger Dedicated Line．The execution point of ZX-3／2 needs to be set up Oil the 6G track．when the train runs from the yard I to the 6G track．The train control grade transition from CTCS-3 to CTCS-2 is realized by expanding the GSM-R coverage scope and setting up the action point of ZX-3／2 on section of Jiujiang direction，When the train departure from the 5G track of the yard I． (4)The temporary speed restriction is achieved by the temporary speed restriction server(TSRS)and the secure data network．(5)This signal scheme is a reference for some similar projects．
