Something rare has occurred for the MTA, they were ahead of schedule and under their budget for the L-Train project. Originally they were going to shut down the entire subway line for necessary repairs from Hurricane Sandy that sent real estate values in Brooklyn down overnight. In Jan 2019 they had announced to do a "slowdown" consisting of reduced service on nights and weekends. In the end, they finished three weeks early and had $100M leftover.
L-Train "Slowdown" Is Over!!
