There are six main branches: to Lewisham in the south, Stratford and Stratford International in the north, Beckton and Woolwich Arsenal in the east, and City of London in the west. This station, Poplar, is at the heart of the DLR system. This is where north/south and east west branches cross and there is also a depot here.
