UPDATE: There are also no DLR services running between Poplar/Canary Wharf and Bank
ORIGINAL: A signal issue at Lewisham has blocked Southeastern rail lines this morning with some trains stuck.
Network Rail are in control of signalling and Lewisham fails regularly. It has sometimes recently seen regular disruption at such an important junction.
Lines are believed to be reopening but with long delays. Passengers can use buses and DLR if you can squeeze onto them.
