Oh, yes! How did I miss Chuck Yungkurth and the Gump Stump and Snowshoe! It was ranked by Linn Westcott as the greaterst small layout design in the history of the hobby. And, as Joe points out, it’s probably been copied/built by hobbyists more times in the past 50 or so years than any other layout ever to appear in the pages of MR (the “Time-Saver” was a switching puzzle or game, the “GS&S” was a layout).
Interestingly, when I had an exchanged of correspondence with Chuck a few years back, he didn’t quite feel quite the same way Linn did about his design, lamenting that he should have included a run-around somewhere along the line to improve operations. Nevertheless, it is the basic trackplan used today on City Classic’s fine trainshow layout that currently tours the country. Talk about longevity!
It’s worth noting that the City Classics version is quite a bit larger than the orginal and includes the key run-around. I agree with Mr. Yungkurth, the layout’s immensely improved with a runaround, small or large implementation.
