The route took us past Thamesmead (mostly social housing developments built in the late 1960s) and Crossness Pumping Station (a sewage pumping station designed by engineer Sir Joseph Bazalgette at the eastern end of the Southern Outfall Sewer). The latter is a Grade I listed building and looks like a must see for fans of steam engines and Victorian engineers. Write up of the route: http://www.thames-path.org.uk/thames_charlton_crayford.html
It was a glorious sunny day as we set off and stayed that way. The one downside of this stretch was the absence of anything other than housing and industrial estates; no shops and no pubs for our normal lunch stop. As a result we kept walking and, after nearly three hours uninterrupted walking, decided to call it a day and peeled off at Erith for the train home.
