exloc subway train

Got the idea when studying DNA replication. instead of stopping, the left side of the train would be for people staying on, the right side for those exiting. the trains would have bilateral symmetry be joined with electrolocks in the middle with a third rail (actually fourth third carries the juice) dead center. the train would come apart just before stations. passengers would enter the right hemitrain at the station and there would be a merging rail where the trains are "conjugated". that is a waiting loaded train hooked up as the train departs and the old right hemitrain is unloaded.

This would be expensive and complicated to retrofit to an existing system, BUT would have multiple uses. say you want to go to Queens while your friend goes to party in da Boogeydown (Bronx) you both start out on the same train in Grenwich Village. . HE stays on the left hemitrain, you exit the last Manhattan station on the right hemitrain and get off in Kew Gardens, while he gets off at Yankee Stadium.

DANG, I should patent this instead of blabbing.
