NEWARK, N.J. — NJ Transit has been dealing with a persistent issue of cloudy and foggy windows on its multilevel rail cars, frustrating commuters who struggle to see station signs or enjoy the scenery during their rides.
The problem is not simply dirt buildup but rather the degradation of the polycarbonate material used in the windows. Exposure to ultraviolet rays, heat, acid rain, and other environmental factors has caused the material to cloud over time, making the windows appear dirty and reducing visibility. This has created both aesthetic and functional concerns, particularly when onboard audio announcements fail.
NJ Transit has attempted various cleaning methods and even partnered with Rutgers University to explore possible solutions. However, after years of trial and error, the agency determined that full window replacement was the only viable long-term fix.
The cost of the replacement project has increased significantly. In 2022, NJ Transit announced an $8 million plan to replace the windows on 429 multilevel rail cars.
By September 2024, that cost had risen to $15 million, possibly due to inflation, labor costs, and material changes. The replacement process, which involves swapping out approximately 15,000 windows across the fleet, is being conducted in phases during scheduled maintenance to minimize service disruptions.
Despite the high cost, NJ Transit officials say the investment is necessary to improve passenger experience and ensure clear visibility for years to come.
