The line of telegraph poles adjacent to the railway at Sterns vividly illustrates the ground movements that have taken place. One post which stood next to the track until shortly before 1979 has been carried a significant distance towards the river by slips since that time and is now only just visible in the trees towards the river. The post is mentioned in the Railway's From The Window booklet as one of the items to see during the journey and it carries a yellow flash to make it more visible.
SVRSevern Valley Railway News and newsletters regularly refer to repair work at Sterns. Some examples are as follows.
Over the winter of 1976-77, intense cold followed by heavy rain resulted in the line dropping 2ft 6" and moving 4ft nearer the river. Permanent way work in progress at Borle Viaduct was halted while repairs were carried out at Sterns. Remedial work enabled the line to re-open in March with trains passing Sterns at the slowest possible speed, repairs there being completed some three weeks later.
In 1994-95 ten feet of river bank was washed away, triggering further slippage. 3,000 tons of rock was deposited on the river bank as a temporary measure to protect the bottom of the embankment from further erosion and to 'toe-load' the slip area. A large ditch was also dug alongside the line on the uphill side.
In the Summer 2007 storm damage, the first severe thunderstorm did not affect Sterns. However further slips began in the following weeks as the wet weather continued, both at the area normally affected and further to the north by Sterns Cottage, the house alongside the line on the side nearer the river.
Part of the solution involved building a 150 foot long piled concrete retaining wall alongside Sterns Cottage. This required 75 24-foot long vertical piles reinforced by 37 42-foot long angled soil-nails and covered by a concrete cap.
In mid-February 2014 evidence emerged that further subsidence was taking place when a significant dip in the line appeared at the north end of the Sterns area close to Sterns Cottage. A 'stop and proceed with caution' restriction was put in place until repairs could be completed over the following months. A large concrete sleeper wall was built at the toe of the slip and packed behind with approximately 150 tonnes of ballast. This was topped off with around 200 tonnes of graded stone in order to help to stabilise the slip and drain the water from the embankment. Full-time staff, with the help of hired in plant completed the repairs to the line.
Following extensive flooding in February 2020 land movements were again observed. A comprehensive drainage network was proposed to collect rainwater and transport it to the river in an efficient manner before it could get down to the slip planes and exacerbate the problem. Contractors Walsh Construction completed this water management work by 29 July as planned, with the final item being the lining of the existing drainage ditch with concrete canvas. The work was funded by £120,000 from the SVR Charitable Trust.
In spring of 2022 Walsh and SVRSevern Valley Railway staff undertook a further project. A deep area of ballast had developed from successive tamping over the years. 300 cubic metres of embankment comprising around 150 tonnes of ballast and 650 tonnes of fill material were replaced with around 400 tonnes of Leca (lightweight expanded clay aggregate) and 40-60 tonnes of ballast. This reduced the weight on the embankment, thereby lessening the progressive movement.
Both projects are hoped to mitigate the problems, but neither is intended to provide a lasting solution.
Electronic ‘tilt monitoring’ equipment was fitted in February 2021. Following the insolvency of the provider this was taken out of use in 2023.
The section of line through Sterns was for many years under a strict 5mph speed limit, with the drainage improvements and earthworks in 2013/14 finally allowing for the limit to be increased to 15mph (although further ground movement led to the reinstatement of a lower temporary speed limit soon after). A consequence of this speed restriction is that northbound trains are made to work harder as they are prevented from 'taking a run' at Eardington Bank.
Access for photography
Travelling South on the B4555 follow the road past Eardington station. A large layby can be found on the right hand side of the road which is ideally suited to the location at Sterns, accessed via the left turn just before the road diverges underneath the railway.
