Herewith some comments.
Good level of completion and much that was right; however also many things which weren't good either. Actually it was some of the more simple things that let you down- knowledge of the correct symbols to use rather more than fundamental signalling misunderstanding I feel, though there were a few examples of those as well.
Hence have tended to concentrate my comments at picking up a lot of generally small things (that in total significantly detract from the impression) in each locality, rather than discuss in depth the signalling of this particular layout since these are the things you need to concentrate on first.
It was certainly a very useful first attempt though; broadly along the right lines- very inital impression was that it looked good but it lthen ost its shine when began to look in more detail.
The good news though is that you have a clear picture at what you must aim to produce in the exam; a lot of people have difficulty in getting started at all but you launched in. The result is that you have produced something substantial enough for me to get a good idea of what things are going wrong. Hopefully you can now take these comments on board and eliminate many of these bugs; if so your next attempt should look much better.
