These sheds were in use until 1948, when the North-West Railway was amalgamated into the newly-formed British Railways. BR built the new sheds at Knapford, and Tidmouth was downgraded.
In Bad Water, the Old Tidmouth Sheds was the Main Line engine shed in 1923 before the Knapford Sheds were built. Sir Topham Hatt I introduced Sir Charles Topham Hatt, his son, at age nine to Gordon from the newly formed London and North Eastern Railway. It was here Gordon was introduced to Thomas, Edward, Henry, Alfred and Winston. After the 1923 accident, the investigations and interviews conducted by the railway inspectors were set here.
