The locally-promoted Elsenham & Thaxted Light Railway was intended to relieve agricultural distress and to be extended to Great Bardfield, over ten miles from Elsenham. In the event, despite the GER paying half the capital cost and a large grant of £33,000 from the Treasury, little local capital was raised and there was a five-year interlude between the granting of the Light Railway order in 1906 and the start of construction in 1911.
The line eventually stopped a mile short of Thaxted church and was opened on 1st April 1913. Typically of light railways of the period, Elsenham & Thaxted was built with few earthworks; steep gradients, only one bridge, and ungated level-crossings with cattle guards wherever possible. As a light railway, it was limited to 25 miles per hour (40 km/h) giving a journey time of 22-28 minutes. There were 5 down and 4 up trains per day on opening.
At Elsenham there was the connection with the main line and a small goods yard. The passengers were usually few in number. A few trucks generally followed the passenger coaches. The conductor/guard issued thin white paper tickets straight to the passengers like a bus conductor; there were no through bookings. The train slowed down to 10 mph for the ungated crossings picking-up or setting-down at the halts if necessary. There were no signals on the line as only one engine was used on the line at one time. The line was absorbed into the LNER on 1st January 1923.
A pleasant line in the middle of Essex it was an early victim of closure as it was slow and poorly connected for passengers and only offered two sidings for goods, so that goods services ceased only a year after passenger trains stopped running in 1952.
Mill Road Halt was located 70 chains (1.41 km) from Elsenham station. It came later than the other stations on the line, being opened 18th December 1922. The station building was located on the west side of Mill Road, and was later demolished after closing. Nothing remains of it.
I wouldn't recommend parking opposite the footpath, or outside the farm - I suggest parking further down the road. This cache is on the footpath, right on the former track bed. Please stick to the PRoW, as the surrounding area is private and they have had issues with people trespassing.
