a maglev trip will be less so that even with the longer trips where the maglev
vehicles don't have the time advantage they will have the cost advantage.
Because land is costly and scarc ...

ARPANET grew during the 1970's as more and more supercomputer stations
were added. The users of ARPANET had changed the high speed network to an
electronic post office. Scientists and researchers used ARPANET to collaborate
