 After a number of failed attempts, in 1865 Sir John Rennie built a jetty and a branch railway, but the company failed financially.The site was acquired and Dagenham Dock was constructed over from 1887 by Samuel Williams.Early in the 20th century, HMS "Thunderer", the last major warship built on the Thames, was fitted out at a new jetty, still known as the Thunderer Jetty.
