Google Earth shows what looks like a open cutting on the DLR just east
of Woolwich Arsenal station. Is that correct? I thought the station

The station isn't particularly deep, it's only a short escalator down from SE platform level to DLR platform level. There definitely is a stretch of track that is open to the air between Woolwich Arsenal DLR and the tunnel under the river (I use the connection to get between N Kent and LCY moderately frequently).
