Hi Simon,
I definitely won't shoot you down because I'm really flattered by your very kind comments. I will admit to being pleased with the layout, and also to not actually knowing how it would turn out while I was building it. I think my aims, and understanding of what I wanted to do developed as I was going along. Also, I did stay way from the things that frighten me. For instance, before starting Old Parrock I tried DCC, and was so bad at it that by the time I'd called Helen (my wife) to rescue me and re-set it for the third time, I realised that it would never work for me. Being IT-literate, it was all obvious to her, whereas to me it was a mystery and therefore a huge stress. The other thing I stayed away from was signals, and that is definitely one aspect of model railways that I must tackle. I've made a commitment that when I start my next layout, hopefully sometime in 2022, I'll build all the signals first.
Old Parrock is now booked for two shows next year; Railex at Aylesbury in June, and Uckfield in October, so this week I've been working on making sure everything is fixed down and all wires and connections are secure - I want it to be bomb-proof!
There are some beautiful layouts described on this forum, and I love the way we all do things slightly differently, What a great hobby!
