2008 CTs on 2012 IRSE tables

[DLMC]

I have a question of 124B(M). As it is already mentioned that present of 126B is required before set 124B(M). Then why shall we consider the 152A(M), 156A(M), pt 242 status etc in 124 CT? I think those consider shall list in 126 CT weather in 124 CT.

Please comment. Thank you.

Looking at your Notes sheet first-



124B(M)-
You seemed to decide not to show as opposing locking 152A(M) on the basis that there is no overlap via 236R beyond 131. However the train can stop at 131 and the overlap will time out, releaseing the locking on 236. Still don't want to be able to set 124B(M) so that opposing locking was in fact needed after all. Similarly from 156 etc.

Same comment re the approach release using BG Q; since this is even further from the signal than the previous case, the opportunity for signal clearance and thereafter signal reversion is even more likely as things are at present on your CT.

Another thing is that the aspect should be proving that there is no premature release stored for 149; hence FH Q should be proved "not operated" and indeed any stick circuit or timer implementing the aapproach release of 149 should be down proved- similar to Raynes Park control (that is usually shown on NR control tables by $16 against the relevant track).

So pssibly just a few things to learn and tighten up on, but overall another set of CTs to be proud to have shared; I am sure that many other users of this website will gain from looking at your attempts.

I'll try to look at the points tomorrow.

Feedback and comments please?
