Single Line Working was eventually, and I stress, EVENTUALLY put in place to get the stranded trains moving. A disgraceful example of how long it takes to set up a method of working when the railway goes wrong.
Let's look at the facts shall we? A broken rail in one of the longest railway tunnels in the UK. A safety inspection has to take place which means blocking both lines.
First of staff need to drive to the nearest access point. The staff then have to walk to the location of suspected broken rail over ballast from the nearest access point, which lets say is exactly half way in the tunnel, is possibly nigh on 1.5 miles maybe more. Then actually do a safety inspection of the track and site around the defect. After that there is the walk back to the access point. Next is the decision that single line working can be introduced, and so more staff are mobilised to the set this up at the required crossovers on the line, which means staff driving and accessing these locations.
So that's time driving to the nearest access point, time walking to the defect, time inspecting the defect, time walking back to the access point, time mobilising staff to locations where single line working can be set up.
All of this in a long tunnel in the middle of the Peak District where road access is not exactly at a premium. Granted if it had happened on the line between say Bolton and Salford Crescent which is easily accessed with one short tunnel section it would have been done quickly.
But due to the location of the defect, it what is probably the worst location for it to happen it took a lot longer. So do tell us how you would have gotten single line working up and running any quicker than the guys (& girls/other genders) who do it for a living could......
