I began this in 2012, in parallel with renovating the house. Starting at the top to clear the clutter in the loft and add more insulation meant it was easier to dismantle most of the railway to do so. I then rebuilt it and converted it to a continuous run. Much of that phase was in 2012/13. As the living room was due to be completely stripped out anyway I used it for some of the larger work downstairs. Only a single man can get away with using a circular saw in the living room because if he wasn’t single he soon would be! ;-) The house took up most of the time from then until 2020 from when more of the smaller projects could be done on the workbench or out the back. More return loops were also added.
