A number of reasons, but mainly because I don't like the concept of a
computer driving my train.   The ATP would have to account for the
worst braking train in the worst conditions (say a K set going down 1
in 30 in the rain).  When you get an S set with good brakes going up a
1 in 30, you would apply the brakes much later, but the computer would
dump the air.

QR has a lot of trouble with ATP dumping the brake pipe on their
trains, and they have made the decision not to install it on their
suburban trains.
