Probably. If I understand the timer suggested above, you momentarily press a pushbutton switch to activate a timed-closure of the relay. So this relay would momentarily cut power to the subway for the 15-25 seconds...then reapply power.
As to emulating the pushbutton trigger, this requires momentarily shorting together the two wires. You could do this, for example, by placing a 10 cent magnet on the lead subway car which trips a 50-cent magnetic reed switch as it approaches the station platform.
