The hidden brook beneath the railway.
Worsley Brook Great Culvert is a brick-lined tunnel that carries Worsley Brook beneath the Liverpool and Manchester Railway. Hidden beneath the Barton Embankment near Barton Moss, it allows the brook to pass under the railway without disturbing the track above. Only a short section is visible at each end but the culvert extends beneath the embankment following the course of the brook.
Why it matters
At first glance you might not think much of it but this structure is actually one of the largest on the line. Listed in 1830 as one of the official structures of the Liverpool and Manchester Railway the culvert was recorded as being 125 feet long and 13 feet wide. It was the longest of several crossings built for watercourses along the route.
Its purpose was to manage natural drainage and protect the stability of the embankment which was raised over low-lying ground and small valleys. Though not visually dramatic it played a crucial role in keeping the railway dry secure and in operation.
