Channel Tunnel

Also see Channel Tunnel Co
1868 A committee was formed to promote the idea of a Channel Tunnel; discussions and experiments continued for 4 years.
1872 The Channel Tunnel Co was incorporated.
1882 The South Eastern Railway updated their plans, proposing to run their line from the tunnel down the Alkham Valley joining the South-Eastern main line at the pier station. This would bring the entrance and approach to the tunnel well within the range of the defences of the garrison of Dover. A branch line would also connect to the London, Chatham, and Dover line at the upper end of the town. The Channel Tunnel Company had reverted to their old scheme of commencing a descent to the base of the tunnel at St. Margaret's, about three miles from Dover[1].
1883 Experimental borings to investigate the feasibility of constructing a Channel Tunnel were halted by the Board of Trade in 1883.
1930 A group of 6 contractors agreed to fund putting a bill through Parliament and obtaining necessary geological information for the Channel Tunnel Co and had agreed to build the British half of the tunnel[2]
