This has been because I have been finishing the Quarry Hunslet for the Stoneleigh 16mm show - http://16mm-ng.blogspot.com/2010/03/done.html and also as we are doing up the house (part DIY, part professionals).
I do hope to complete the trackwork on the yard board as soon as the new boiler is in and the radiator in my study replaced. Until then the whole study is in a state of flux.
