An un-gated crossing, I designed for a narrow gauge layout. It will however just fit a standard track and for most tracks will give you the correct rail only accross the road. it should stop all traffic but now and then after the trigger point but when the train is still some distance from the crossing, one will slow down and then nip across, this seems to be what a lot of drivers do anyway, so i left it as is. Have fun. Belkenn
