At our running day last Saturday, we had trouble with one engine when it's eccentrics hit a concreted level crossing on it's approach to the steaming bays. The concrete was above the rail height with flangeways to allow wheels through. Obviously the concrete should not have been like this and was swiftly chipped back, and the club is doing what it can to fix the damaged engine.
However, this raises a question. What clearance should be allowed above rail height? There must be some, if only to allow for inaccuracies or wear in multi-gauge points (our 3.5" rail does not get nearly as much wear as our 5" rail). But are there standards for this clearance? If there are no standards, what would we regard as an acceptable clearance above rail height? 3mm has been discussed down at the club but it sounds quite a lot to me.
