At the time of the earliest railways, the town of
Hadleigh was an important centre of the wool and clothing industry. The
Eastern Counties Railway was incorporated in 1836 to build a railway from London to
Yarmouth; the capital was £1.6 million. This was a prodigious project, and in fact the actual cost greatly overran, so that all the money was spent and the railway only reached
Colchester. When the ECR reappraised its plans, it proposed to build from Colchester to Bury St Edmunds through Hadleigh, putting Ipswich on a branch from the town, but this scheme came to nothing. Local interests were dismayed that their railway connections was to be denied to them, and in 1844 the
Eastern Union Railway was incorporated, to build from
Ipswich to Colchester, possibly to include
Norwich in its network. However this line was not to connect Hadleigh, and by 1844 merchants in the town had seen the adverse effect on formerly prosperous towns that were by-passed by main lines. Local people promoted a branch line scheme to connect Hadleigh with
Bentley station on the Eastern Union Railway main line, seven miles away. There was intense competition between the Eastern Union Railway and the rival Eastern Counties Railway: the object was to capture as much territory as possible. From the EUR point of view, the Hadleigh branch would cut off the possible advance of the ECR. Accordingly the EUR supported the local scheme, which was nevertheless promoted in Parliament as an independent project. ==Authorisation and construction==
