1997 Layout CT for Routes from 112 and point 306)

[PJW]

Hello PJW,
I started to look at 1997 layout and i did all points CT's; since points required in exam were already discussed there is no point posting them again so instead i am attaching points 302, 304 and 305 CT's and if possible could you please have a look at them and let me know:
1. are the routes ok
2. i am not sure at all what should go on the boxes i left blank so can you please point me towards a document or something that explain what must go in there or if you have time explain to me?
Thank you so much!

Haven't yet looked in any detail (may be the weekend) but the boxes left blank are those that are often blank because they relate to locking that is only rarely needed. Unless the points are facers in an overlap there will be no such locking and even if they are facers then in many cases there will still be no locking.

The bottom row is for Time of Operation locking, variously abbriviated as "T of Op" or "TooL".
The columns to the right are for the "counter conditional locking" associated with swinging an already established overlap by a call on the inge points to the other lie.
I suggest that if you use the Search facility in the top green bar within this website and search for such terms you will find quite a few hits that may help.

Note that because these boes are rarely used and take time to draw oon the blank CT in the exam I advise people not to bother but just leave a very wide comments column to the right of the page and wite in "long hand" on those few occasions when such locking is needed. Hence you'll find several instances of this on examples posted here.
