Heritage Open Day: The Refurbished, Grade II listed, Oswestry South Signal Box will be open for viewing. First built in the 19th century for the Oswestry and Newtown Railway, Oswestry South signal box was operational for over 100 years. Unlike much of the neighbouring railway infrastructure, it escaped demolition but was stripped of its contents and equipment and remained a shell for many years. A Grade II listed building, Cambrian Heritage Railways volunteers have spent countless hours refurbishing the structure and sourcing and installing appropriate equipment. The Signal Box has now been restored for operational use so it is no longer normally available to visit. As public service trains are not running over the HODs weekend it will offer the rare opportunity to have a look around the restored facility and see how it works.
