I've been back home this weekend and have made a start on modifying the track layouts. Luckily removing the original points turned out to be quite easy, just had to cut a few fishplates to remove point's vertically. I have replaced the blank spaces with Peco point plans just to make sure everything will fit, and it does! In fact the entire alterations only require 3 curved radius points extra to what I removed so that's not bad. Pictures below of progress...
I have also received my copy of Model Railway Signalling by C.J Freezer, thank you for the recommendation and it made for an interesting read. I am slightly more clued up on the whole subject. I also received my kit signals from Knightwing, they certainly would pose a challenge to add LED's but not impossible. I have some brass rod in the stores that is ideal to replace the original plastic pole, and the heads should drill out but with a modified back using styrene. I purchased LED's to do the job ages ago, just need sum miniature wire and a steady hand for soldering! A Project for the Christmas holidays... given that us 'part-time' students get 3 weeks!
