There is a provision in the GCR that allows for the specifications to be changed within the first year of a classification or reclassification. That would be one method of handling this if it's an immediate problem...

That works only if the ITAC is willing to admit they made a mistake, and based on Andy's tone when I ask some simple questions semms unlikley.

That would also require enough cars be built in a year to give enough data, again unlikely.
