That of course assumes that "meet" means the front of both trains converge. Maybe "meet" means when the middle of the line of cars of each train converge. Then the longer train would be closer and just like the specs I get nobody define the lenght of the train or the definition of key terms. We all just assume. Which is why I need to get the knowledge of FoxPro as well defined as possible, because most of the work is in being 1. Smart enough to weed through no or little spec to figure out what they really want. 2. Movitated enough to search for the real "spec" burried in the lack thereof. ... Enough preaching for now!
