I’ve done a lot of “armchairing” on this concept over the last couple of years…designing & building an entire layout based entirely on a single industry, rather than the more traditional approach; having multiple industries on a single layout… Up until now, logging layouts are the only ones I’ve seen that practice this in its purest form… (outsideof the odd “micro”, or “pizza” layout.) You may think that building this type of layout would inherently mean it would have to be small…this is not necessarily true…size isn’t really that much of a factor…It’s a great design concept for a large, or small layout. Building a large layout this way would free up a lot of real estate for more prototypical things like larger structures, longer, multiple sidings, storage tracks, longer mainline runs…The advantages for a small layout are obvious… The single-industry concept lends itself perfectly to point-to-point operations…Industry pick-ups/drop-offs, main, or branch run to terminal/interchange…Continuous-rum setups could be made to work as well…perhaps with the industry switching on & off of a continuous running main… A few years back, I saw an idea in MR showing some ideas for designing a single-industry layout centered around the auto industry… My reason for posting this was to possibly get some discussion going…I’d love to get some feedback on this…any thoughts on this idea, pro or con…? Has anyone built a layout like this? Planning on it?
