| What’s a good height for an overpass? From Michael Hader: ! Matthew Bates has created a good tutorial for overpasses and inclines: http://ourworld.compuserve.com/homepages/train_depot/inclines.htm From Larry Pieniazek: ! At least 13 bricks if not higher. The trick is figuring the slope of track leading up to the overpass. The track slope is limited by the horsepower-to-weight ratio. As you increase the slope, slippage also comes into play. At 3 plates per track segment you are going to have a hard time pulling even 1 or 2 cars up a grade with a single motor. A motor by itself will have a hard time at 4 plates per slope unless you add extra weight to improve adhesion. I tend to use 1 plate per slope, but I like long trains and usually budget 2 motors per locomotive. Also, allow for transitions. Do not change the rate of change in elevation by more than 1 plate per section, so to get to that monster 4 plates grade, you should be using 3 transition segments of 1, 2, and 3 plates of increase. Never change the rate of change on a curve, or on the section next to it. You can get away with two plates per section, even curved, without derailments, if you come into and exit the curve at the same grade. |
