Route Control Tables 2004

[PJW]

Here are your first route CTs.

I missed one, so here it is

142B(M)

Not a bad attempt at a complicated CT.
For opposing moves you missed those that route to 135 but you did see that 107 and 142B(M) do sometimes share an overlap, though you should have made this conditional on 203.

You need to worry about foul tracks BM and EH; the former you can get rid of by calling 208N and then detecting it, but gives slightly more availability by demanding (208N or BM clr) thoughif the signaller then handsignalled from 125 due to the lack of point detection then an aspect reversion would occur. Conversely 206 are best left normal or else the trapping from the siding is destroyed.

Just because it has a PLJI does not necessarily mean that signalis approach released- it depends on the differential speed; however all you have to do is FOLLOW THE ROUTE TABLE INFO.

For modern (i.e. fibre optic or LED) banners it s only necessary to prove that it is not displaying ON in order for the signal in rear to clear to better than yellow- it need not actually be alight.

I'll deal with swinging overlap and comprehensive A/L separately.
