Rail capacity: how to check

[Strela]

Thanks all for the commentary. Of course the multiple PDT files would solve the issue. VM agree that makes sense regarding the number to be provided for rail movement - actually had done what you suggested ie. halved the initial expected requirement. With the nature of the project I am working on (you know what it is..) there is an additional requirement on rail that requires a rigid number per operation.

Anyway a solution has been provied by the brains trust in record time - thank you all :)
