Addison Colliery Railway Tunnel

Mineral lines from Crawcrook and Greenside ran to Stargate Pit (HER 3319) where the coal was transferred on to wagons that ran down an incline (HER 5038), then through this tunnel under the road in the grounds of the coal company offices (HER 5036) to Addison Colliery (HER 5033). A second tunnel was eventually built because the first was too small for the 17 ton trucks that replaced the older 10 ton trucks on the incline. The coal was then taken by rail to markets all over the country.
The second tunnel is shown to the east of the old tunnel on the Ordnance Survey 25 inch map of 1920.
