Hi Arnut
A good set of control tables which should do well.
Overall, most of the conditions have been well handled.
best wishes

Some quick comments:
Route 216A(M)
opposing route locking applied by route 327A(M) should also require FZ sectional overlap locking free
timing to a stand on FH / GF tracks is a little long. My "rule of thumb" is track length (metres) / 10 + 10s, giving approx 20s in this case.
(BT or 137R) also needed in track circuits, as it is foul of the overlap via 139R
The FY aspect is not permitted to 212 with JI position 1 - see route tables.
references to 212 should also specify Left and Right aspects of 212 Banner repeater.
222 is not a controlled signal, so cannot be said to be ARAFOAL
348C(M)
does not require137N - does not provide flank protection
323A(M) does not exist - not a stop signal.
should instead require single line release 321 N
Also requires route 343A(M) Normal (directly opposing overlap)
FP should also be in the lookback tracks
Approach locking timer could reduce to 60s
349D©
should also require 135N (flank)?
your track clear conditions are for a main class route
buffer stop lights are not controlled or lamp proved, so cannot be referred to as a "signal ahead aspect"
133 points
N-R should require (FJ or 132R) - foul track
R-N should not require FJ clear - in the N alignment FJ is "in line" not foul
should be set N by 347B(M) - flank protection
It looks like you have interpreted route 346C(M) to be routed via 146R, 133R - this is an odd choice given that there is a straighter option via 146N , 133N - the table of routes indicates no alternative routes so I would expect this would be the one and only option.
