I love signalling, and modelling signalling systems. In the future I have a plan for an exhibition layout running under catenary, fully signalled using automatic block signals. For now though the plan is to get the current layout done.
In the meantime we can all enjoy some great old video – thanks to YouTube.

I love these old videos and collect them when I can. This one is great, and shows a lot of features of the steam era railroad that you might not otherwise notice.
