Automation
A pair of R188 trains approach 111th St station on the Flushing Line. The (7) train at left is operating under automatic train control on the CBTC-equipped main track, and the out-of-service one at right is (to my knowledge) being operated manually by the yard operator into the pocket track. This also explains the difference in speed between the two trains, as the one at right was creeping along very slowly and the one at left was easily going three times as fast! It was quite lucky that they met in the clear space where they did!
