Nostrand Junction Bottleneck

In Central Brooklyn, a dreaded subway bottleneck grinds trains to a halt

A subway bottleneck in Brooklyn has for decades caused headaches for hundreds of thousands of commuters on the city’s busiest subway lines.

Trains on the 2, 3, 4 and 5 lines all intersect in Crown Heights beneath Eastern Parkway and Nostrand Avenue. There, trains on the 2 and 5 lines turn south to run beneath the avenue, while trains on the 3 and 4 lines continue east beneath the parkway. When a train makes a turn, others must stop for a minute or two until the track signal ahead turns from red to green.

This is the Nostrand Junction. A delicate dance happens there hundreds of times per day – and it's an inconvenience familiar to all who pass through.
