Alexandra Docks and Railway (ADR)

The Alexandra (Newport and South Wales) Docks and Railway (ADR) was a company formed in 1882 from the former Newport Dock Company of 1865.  The Newport Dock Company had built an earlier dock that was now outgrown.

Prior to 1914 the Alexandra Docks were superlative in the world in terms of water area within the docks and ability to handle large vessels. The decline of the mineral extractive industries of South Wales resulted in a corresponding decline of activity by the ADR and its successor owners. However it is now active and successful as a general dock facility as part of Associated British Ports.
