No. 7 train riders looking to race from the subway platform to home plate at Shea Stadium should look for the diamond.
On No. 7 trains, red diamond means express, a green circle for local
NYC Transit has begun rolling out subway trains with new digital signs brightly declaring if they are running express or local: a red diamond for express, a green circle for local.
The first train fully loaded with the broadsides hit the rails during last night's rush. More subway cars will be rigged in the coming weeks and months.
