This makes the third time I have added on to my layout since I moved into my current house 3 1/2 years ago. I have now officially taken over the entire basement. Doing so was not an easy task as I had to take in account access to circuit breaker panel and such, (my folks gave me the green light on expanding as long as I took that into consideration). Not a problem there, just constructed another lift up bridge and expanded the operating pit as the walkway to the new section of layout. I was able to remove an old incinerator thus giving me the room to span out the framework. Here is a video clip of the layout as of July 10, bear in mind the layout is messy due to all the work.
