Brio/Ikea Bridge less steep

The reduced inclines means our electric trains can now drive up without failing. Its increased in length but still fits on the pretty standard 250mm build plates. You can use the trestles of the original. So one of our 2 trains can go up now, the other doesn't have enough traction on the plastic surface. I might try to print thin TPU strips to place inside the tracks for more grip. If I have more time for a future improvement, I'd try to roughen up the rail surface texture to increase grip that way.
