YLP Wrote:2. Bite 6 Opposing route locking (Point 10)
- If there is really an opp. route infringing one side of the swinging O/L only, do I just ignore it? or I just write it without a point condition (of the swinging O/L point?)
Some people when writing the string of tracks that impose locking after a route used start writing point conditions within that list, almost as if it were the tracks in aspect for a swinging overlap; this is wrong!
Generally if there is a swinging overlap within the "opposing route" for the one for which you are writing the CT, then one lie of the points opposes your route and one does not. You should list all the tracks for the route and the lie of the points that oppose but then condition out THE WHOLE LOT (including the Route Normal) by the availability of the set of hinge points to swing away and thus no longer oppose the CT route. Having written (I think in 2005) that to get such an example in IRSE Exam would be unusual, just look at the 2006 layout and the recent comments I gave Alex where there was not just the one example, but several! Just goes to show that you may have to cope with anything......
