 tunnel, which the railway tunnel crosses at an acute angle and slightly higher. Because the canal tunnel was lined with clay "puddle" it collects water which ends up in the rail tunnel making the latter very wet. This continues to cause problems: between 1983 and 1985 the tunnel underwent extensive engineering works http://news.bbc.co.uk/local/hampshire/hi/people_and_places/history/newsid_8383000/8383071.stm, and the line through it was worked as a single line for long periods while remedial work was carried out.. A narrow gauge railway was set up as part of these works.
