Where do car body lights need NOT be extinguished during daylight hours?

The requirement for car body lights to be extinguished during daylight hours depends on specific regulations and safety practices determined by the train operating authority or system. In the context of the question, the area from Marcy Avenue to 168th Street on the Jamaica Line is designated as a space where car body lights can remain illuminated even during daylight hours. This is typically because this stretch may have higher ridership or specific visibility concerns that necessitate lights being on for safety and identification purposes.

In contrast, busy urban areas like Times Square and major transit hubs such as Rockefeller Center and Grand Central Station usually have stringent regulations regarding light usage to minimize visual clutter and enhance overall operational efficiency. Coney Island Station, being a terminal station, may have its own set of operational protocols that require lights to be turned off when not necessary. Hence, the specific characteristics and regulations of the segment on the Jamaica Line explain why car body lights are not required to be extinguished there during daylight.
