This dilapidated building is hidden away in a public park near Harry Wright Lake.
It’s probably an old storehouse. On it was a mural of The Blue Comet, which last passed through the town in 1941. The mural is faded and chipping badly, and has been ignored, as is the building. A sign of days gone by. Weeds are overgrown around the building.
The Blue Comet was recently memorialized in the TV show the Sopranos. It was when Bobby gets murdered when he is buying the Blue Comet toy train.
There are many tributes to The Blue Comet in NJ and train lore.
