The Middy, which in its heyday was a branch line which ran for just 19 miles (31 km) from Haughley to Laxfield, Suffolk. The line became part of the London and North Eastern Railway in 1924 and the last trains ran on 26 July 1952.
The line was intended to run from Haughley to Halesworth, with a second branch running from Kenton station to Westerfield near Ipswich and was built to provide transport to the rural Suffolk communities who had no reliable transport links. It was built in accordance with the 1896 Light Railways Act, which allowed for cheaper construction methods in return for a speed restriction of 25 mph. The railway was built as cheaply as possible: the buildings were constructed using corrugated iron, and the route followed the natural contours of the land to minimise the need for embankments and bridges. The section from Haughley to Laxfield was completed and open for passenger traffic. Beyond Laxfield the line was built for approx mile to Cratfield over which an occasional freight train was run but the section fell into disuse. Some earthworks were begun between Cratfield and Halesworth but these were soon abandoned with now no evidence remaining. The section of about two miles of the branch from Kenton to Westerfield was completed as far as Debenham and a few goods trains were run but this also was soon abandoned. Some sections of trackbed and embankments still survive.
A short section of track at the former Wetheringsett cum Brockford Station has in recent years been maintained as a heritage site by a small group of steam enthusiasts.
