Emergency services are at the scene near Lewisham.
The crash happened in the rush-hour on the main line into Charing Cross. The trains are operated by Connex South East.
There was little damage and no smashed windows in the low-speed impact which happened at around 8.30 a.m., a Railtrack spokesman said.
