At the moment, in the grain industry the data is collected from a certain group of shippers in terms of how many people have actually used interswitching, how many cars they've moved, and to some extent the money savings they've achieved from just the behaviour change of the railways willing to supply them the business and not do the interswitch. Generally that kind of information is going to be with the shipper. It's not necessarily publicly available information unless an industry like ours is willing to start to correlate that kind of information.
