Overview

• A breaker tripped just before 8:30 a.m. at West Fourth Street, cutting signal power and freezing A, B, C, F and M trains under red signals.
• MTA crews deployed a generator truck by 9:30 a.m. and had cleared all stranded trains from the affected area by 10 a.m.
• B and C services remain fully suspended this afternoon while A, D and M lines are partially halted and F trains operate on rerouted tracks.
• E and G lines continue to experience delays as rerouted trains share signal infrastructure, increasing wait times.
• NYC Transit President Demetrius Crichlow identified a tripped breaker as the cause and flagged potential heat-related stress on the aging electrical system.
