Interchange Stations

Passengers can take the long loop from ANHEQIAO North station to TIAN'GONGYUAN station without interchange. Passengers taking short loop from north to south could change to train at the opposite side of the same platform (No need to go through passage way or other ways) at XIN'GONG station in case they need to travel south further in TIAN'GONGYUAN direction.

To give passengers clear information on trains at long loop and short loop, PIS at all stations of BJL4 and inside trains will display the terminus of each train. Together with PA, passengers will know which train is to XIN'GONG and which train is to TIAN'GONGYUAN and board the right train.
