" The quiet Rea Valley of southern Shropshire changed little during the 19thC. Essentially rural, its lack of proper communications caused it to remain virtually unknown to the rest of the world. Roads and railways grew up to surround the region at a distance but nothing of any great importance penetrated up the valley. It was not that local rail development was never advocated: such schemes as the Ludlow, Bridgenorth and Wolverhampton Railway would have cut right across the district, but they were all too un-founded to last. However, as in many other places, the Light Railways Act of 1896 turned what seemed an unlikely dream into a feasible proposition. By the turn of the century a number of local landowners and inhabitants were seriously considering the possibility of promoting a line from the Great Western Railway at Cleobury Mortimer up the valley, with a view to exploiting their not inconsiderable interests there. Chief amongst them was Lord Boyne, for the most important factor in the construction of the railway was to be the opening up of the extensive deposits of Dhu Stone on his estates."
