Hi Paul.
Youll have to be a bit more specific about the circumstances under which this 
is going to happen , as there are a lot of variables.

Things like 
1/ Are flange lubricators in use on the curve.
2/ Is is a once off event or on a regular basis.
3/ The weight of the rail , the type of sleepers and the fastening methods of 
the track to the sleepers.
4/ The speed at which this is likely to happen.

cheers
