I think any multimodal transport has an inherent lag - and I don't think its worth the effort to get the lag out - beyond that because of the inherent delays (you gotta sort the railcar onto a siding, then unload the trailer (if its a can, it needs to be unloaded and mated with a chassis), put it somewhere so it can be picked up, the coordinate to have it picked up by a tractor.) I'd put the effort on getting shippers to accept the longer shipment times - a little less JIT inventory for example, its a change that needs to be made at all levels.
