On a fixed railway crossing, the wheels need only drift by a small angle, say 1 in 20, before the vehicle may start to go in the wrong direction at the V of a V-crossing. This problem can limit the maximum speed of vehicles using the crossing. In addition, the open gap at a fixed V-crossing forms a weak point on the railway line where the heavily loaded wheel must bump across the resulting gap of about 10 cm (4 in), supported only … WebFind many great new & used options and get the best deals for Atlas #2566 30 Degree Crossing Track - N Scale - Code 80 Rails • at the best online prices at eBay!
