When a train goes through the rail tunnel you can feel a blast of air coming along the canal tunnel, so this will help with ventilation.

BW had a £30K bill for replacement batteries last year. As time goes by the batteries hold their charge for less time, with several breakdowns resulting. Another factor must be the huge cost of staffing the present arrangement. >I am, overall, quite surprised at this change. I am not particularly surprised, as BW had carried out exploratory trials last year and user groups have been pressing for a more flexible method of operation. -- Martin Clark Internet Boaters' Database http://www.lock13.co.uk/boats Pennine Waterways Website http://www.penninewaterways.co.uk
