๐ Untangling Brooklyn’s Subway Jams: MTA's Bold Move
The MTA's 2025–2029 Capital Plan includes a major overhaul to eliminate chronic delays at Nostrand Junction, the infamous "Crown Heights Cluster" where the 2, 3, 4, and 5 trains bottleneck east of Franklin Avenue. This config forces trains to criss-cross—causing minute-long backups hundreds of times each day, cascading delays even into Manhattan and the Bronx.
๐ง What’s the MTA Planning?
-
Re‑route Service Patterns
-
2 and 3 trains will stay local to Flatbush Avenue
-
4 train becomes express to Crown Heights–Utica Ave
-
5 train becomes express to New Lots Avenue
-
An “8 train” local service may be reintroduced between Franklin and New Lots to maintain local stops
-
-
Construct New Crossovers
-
Additional track crossovers near Utica–Kingston and Flatbush–Brooklyn College will keep local & express lines fully separated
-
-
Future‑ready Signal Infrastructure
-
Though CBTC upgrades aren’t in this initial phase, the redesign paves the way for safer, higher‑capacity signalling later
-
๐ Traveler Gains
-
Faster Rides: Expected savings of 60+ seconds per rider through Brooklyn, with ripple effects across the system
-
Improved Reliability: Fewer delays from track conflicts will make service times more predictable
๐ Timing & Budget
-
Cost: Included in the $68.4 billion 2025–2029 Capital Plan
-
Start Date: Planning and design underway now; construction slated for the second half of the plan cycle (~2027–2029)
Signal Integration: CBTC budget of ~$5.4 billion may extend to this corridor in the 2030–2034 cycle
๐งฉ Part of a Bigger Picture
-
This junction fix aligns with system-wide modernization efforts:
-
1,500 new subway cars
-
CBTC signaling expansion across Broadway, Liberty Ave, Rockaways, J/Z and more
Elevated structure repairs, flood resilience, ADA upgrades, facility improvements
-
๐ Why It Matters
-
Immediate Rider Impact: Millions of daily commuters in Central Brooklyn will benefit from steadily improved service.
-
System-wide Efficiency: A single bottleneck’s resolution brings tangible improvements across the network.
-
Future Infrastructure Upgrade: Prepares the corridor for smooth implementation of modern signaling.
