The tunnel was repaired, but the continuing effects of subsidence resulted in speed restrictions in the 1950s and closure on 4 April 1960. The eastern portal is still open and accessible, and the tunnel itself is open to a point just west of the second air shaft (counting from the east). Beyond the second air shaft the tunnel has been filled with earth.
The tunnel was fixed, but the ongoing consequences of subsidence led to speed restrictions in the 1950s and closure on April 4, 1960. The eastern entrance remains open, while a section of the tunnel is still accessible from the east, ending just west of the second ventilation shaft. The remaining portion of the tunnel has been filled with soil.
