31 Aug : 18:54 | Q: WHAT ABOUT A DESIGN WITH A DOUBLE TRACK MAINLINE? The question of how to analyze a double track main layout design comes up a lot. Treat one main as mainline, and the other as alternating between connecting track and passing sidings, as you prefer. The end result will be a double tracked layout can move a lot of cars -- which is just what you would expect. However, be aware much of the fun of dispatching is arranging meets and figuring out how to get one train past another. A double track mainline will be less of a challenge to dispatch since few trains will need to pass each other unless there are a lot of locals blocking the main. Such a layout will move lots of trains, so you'd better have lots of staging on each end to supply the double track with trains -- and you'd better have operators who love just rolling off the miles on the main. Many find single track railroads are more interesting operationally -- just something to be aware of. |

23 Sep : 15:52 Reply to this | This had been a tremendous aid in understanding the frailties of my design. It's not a "two scoops, add water" instant design method, but it does provide great insight into the functions of the layout. Thanks so much. I'll be including an LDA summary when I update my blog on MRH. Don |
