I am working this whole weekend- I might get a chance on Monday or Tuesday evening. However if anyone else wishes to comment earlier ....
OK printed, though twhether I actually have time to look at is questionable. However I have looked at calcs; see attached
I've had a look at the layout. Will try to type in response tomorrow.

Actually I had just started looking whe I noticed that Peter has reviewed and will be commenting. Hence I'll leave Peter to write his critique and I'll drop onto doing something else.
However although I had yet to start any form of detailed check and was only looking at "artistic impression" I have to say there is quite a lot of red ink over the plan already.
It features quite a lot of the common howlers (DO READ EXAMINERS COMMENTS AT PREVIOUS YEAR'S EXAM REVIEWS AND MAKE SURE YOU AVOID THE HOWLERS):
# very odd ideas about trap points,
# freight yard with lts of signals and motor points but no track circuiting or explanation how it works safely,
# "facing" LOS,
# preset shunt provided in the middle of nowhere fo no good reason,
# I am yet to understand the supposed method of working on the branch (but I wouldn't travel on it!)
# 552/554 placed on gantry for no good reason and prevents the use of stabling sidings by two 180m trains,
# overlaps just measured to be 180m beyond signal and placed without thought within S&C
# point numbering seems to carelessly miss some, switch diamond looks like double slips
# lack of bufferstop lamps and TCI
# inability to be able to make all operational moves specified
Can't say that I am too impressed so far; impression given is that candidate half knows quite lot of stuff but really hasn't prepared well enough and is somewhat confused. Given that the exam is less than a fortnight away there's a lot to learn in the remaining time.
