I am modelling the late transition era in HO with a mine scene in HOn30 for the 'critter' in my avatar. Most of my locomotives are diesels in Canadian Pacific livery made by InterMountain and Kato. I have a few steamers including Bachmann's Hogwarts Express as well as a kitbashed 4-6-0 which will have early Grand Trunk livery and a few other steamers, mostly switchers, which caught my fancy.
I have built several small operating diesel or gas powered switching engines including a powered Mack 15 ton, 15 ton and 25 ton switchers and a few others. I have also scratch built a galloping goose freight engine and a hi-rail utility truck.
I love LED lighting. I have installed working headlights, tail lights and signal lights in many vehicles. I have made several different street lights and yard lights.
I have not been able to start building my layout yet for a variety of family reasons, but there is a light at the end of the tunnel (when my son moves out). I hope to begin construction within a year or two at the most.
