The subway system requires new signals, switches, cars, and expanded routes. While congestion pricing can’t pay for all of that, it can help.

The chief environmental engineer for the MTA New York City Transit is currently teaching the Capstone Workshop in the Sustainability Management masters program.

The time for a comprehensive fix for this region’s mass transit is long overdue.
