The Great Western Railway (GWR) was one of a number of private British railway companies created to develop the new means of transport. The location of the painting is widely accepted as Maidenhead Railway Bridge, across the River Thames between Taplow and Maidenhead. The view is looking east towards London. The bridge was designed by Isambard Kingdom Brunel and completed in 1838. A tiny hare appears in the bottom right corner of the painting. Some think this is a reference to the limits of technology. Others believe the animal is running in fear of the new machinery and Turner meant to hint at the danger of man's new technology destroying the inherent sublime elements of nature.
