This article was written by Lee Holland who is the tunnel manager and works for the Highways Agency who have responsibility for it on behalf of the Westminster Dept. for Transport. The article is in the Welsh Railway Research Circle's archive, Vol. 3 p. 142 of 6th. Nov. 2002. (www.wrrc.org.uk). Lee has access to much of the historic documentation about the tunnel held by the Highways Agency.
Whilst meetings have had to be postponed, the monthly air quality monitoring visits to the tunnel continue. We have done three so far and there are lots of photos of them in the gallery (go to Media -> Gallery -> Air Quality Monitoring). We test for Carbon Monoxide, Hydrogen Sulphide, Explosive Gases, Oxygen concentration and Volatile Organic Compounds. So far we have found no trace of any noxious or explosive gases. So long as we continue to get these results throughout the year, we will have a library of positive results. When a portal is opened, it should not be necessary to do a long re-test on air quality which could delay re-opening possibly by up to a year. We shall continue to report on these visits on Facebook after each one.
Over the weekend, Steve Mackey & I decided that we would offer to postpone the meeting on the Tunnel’s future arranged for 23rd. March with the Deputy Ministers of Economy & Transport and Culture, Media & Sport because the Welsh Govt. clearly has more urgent priorities at present. The leaders of NPT & RCT who have both been invited have agreed, so therefore the meeting will not go ahead until the current situation has eased.
We have decided to postpone the Annual General Meeting for 2020 because of the current situation with COVID-19. We shall choose a revised date as soon as the situation improves.
We have also been in touch with the Welsh Govt. offering to postpone two meetings that were scheduled for the next two weeks as we expect that they will have more urgent matters to deal with.
