The station to the north of the tunnel is Oakleigh Park (1873) and to the south, New Southgate (1850).
The tunnel was built as part of the Great Northern Railway from 23 April 1849.
60508, Duke of Rothesay, was hauling a passenger train from Edinburgh Waverley when it began to derail inside the tunnel due to a combination of faulty track and excessive speed.
The driver was only slightly hurt but the fireman was killed after he escaped from the engine but was hit by the following carriages.
