The railway put Mead Mill out of business. As the map shows, the new embankment and viaduct required the river channel to be diverted, leaving the old water mill without a water supply or a mill race. I assume that the mill owners made a conscious business decision to close down the mill and take the compensation. By this time (1837) there was less business for local mills and Wolverton could function quite well with use a single mill.
The mill continued to be inhabited, according to subsequent censuses, for another 20 or 30 years. Then it was pulled down and little trace remains.
As this plan illustrates, the embankment and new river course required that the Haversham road be diverted as well.
