My latest article in the commercial press describes an interesting custom HO scale layout design consultation project. It's found in the May/June 2010 issue of Model Railroad Hobbyist mediazine (always available free at the preceding link).
The client's concept, space, and even basic footprint had been well thought-out: a pair of proto-freelanced Canadian branch lines crossing in the Alberta prairie, with grain elevators the primary signature industries.
His original footprint ideas were for an around-the-room arrangement with a movable benchwork section. Although that was certainly workable in the roughly 11 1/2' X 15' space in HO, I always like to at least try for a walk-in footprint. In this case, we were just a little shy on space and the client's original footprint was the better choice.
The MRH article includes some great photos of the region, as well as the track plan and a bit of description on the track planning process and trade-offs. There are even a couple of photos of the benchwork, which is well underway. It was an interesting project and I hope that readers will enjoy the article.
