It's interesting. The Amex is a stadium where they want most out-of-town fans to arrive by bus (either direct or P&R) or by train - so if there are no buses or trains it does make it very difficult to stage a match. Or at least stage a match with a sizeable crowd. Sure us locals, or relative locals, can walk (takes me an hour), but if too many decide to do that then it may get postponed for 'safety reasons'. Can't have the pavements too crowded can we? Someone might get forced off into the road and knocked down. (The good news is at least they won't get knocked down by a bus)
