A large chunk of concrete fell on a vehicle underneath the platforms at Newark Penn Station in early November, according to an NJ Transit police report, the latest in a series of incidents involving deteriorating concrete along the region's rail lines.

The report, which The Record and NorthJersey.com obtained from NJ Transit through an Open Public Records Act request, shows that on Nov. 3, the 10-inch-by-12-inch piece of concrete fell on the hood of a blue Mercedes, causing damage to the vehicle.

No one was injured, but the crumbling concrete is emblematic of the system's age and need of maintenance.

In September and October, NJ Transit suspended service twice on the Gladstone Line after a large section of a concrete retaining wall at Summit Station fell onto the tracks.

An emergency repair was made to the damaged section, but other parts of the wall in Summit are in visibly poor condition.

The concrete wall at Summit station dates to 1902 and was constructed by the Delaware, Lackawanna & Western Railroad. The Lackawanna was one of the first railroads to make extensive use of reinforced concrete in its structures, including stations, viaducts and control towers.

Commuters along NJ Transit's Morris & Essex line see pieces of this history every day, but the concrete walls, stations and highway underpasses are showing their age.

NJ Transit later said it was inspecting other concrete walls in Newark and Montclair. All three walls were constructed more than 100 years ago by the Lackawanna Railroad.

Newark Penn Station was built by the Pennsylvania Railroad in 1937 and designed by McKim, Mead and White, the same architects who designed New York's Penn Station.

The Newark station now serves the passengers of NJ Transit, Amtrak and PATH.

According to the police report, NJ Transit notified Amtrak about the damage.
