The shoe may be worn, then. The groove should be fairly narrow.
The white slider-shoe is 'sprung' in the 'down' position - is this correct?
Yes.
Further, the brakeman car is challenged to go over my 45 degree cross-over too as the white slider-shoe hits the center of the cross over.
Another indication of a worn shoe.
I need actuator blades, tell-tales etc too - any ideas where I could get my hands on these?
