About this 3D model

This trestle system allows for inclines and elevated sections of Fastrack. I have designed sections in 5mm (0.2in) increments. Combining this with 10inch sections of Fastrack will result in a 2% grade. It recommended to place a trestle at each joint, otherwise the track will flex unacceptably. If you you have powerful locomotives and short trains, skip every other piece for a 4% grade. Or throw prototypicality to the wind and use every third part for a 6% grade (or forth part for an 8% grade). For odd grade percentages, an optional spacer is also available. Or mix and match to create easements. Or just make a long flat bridge. I have included the parts to make trestles up to 5 inches (120mm) high, if you need a taller section feel free to message me. Other than the 5mm trestle, each trestle is comprised of two parts; a clip and a base. All parts can be printed without supports. Minimum infill is required as the walls do most of the work.
