This subway tunnel is one of those unlucky few tunnels. In its day, this tunnel was a vital subway link that even hosting LIRR trains. Today though, the areas it served are not as central or popular as they once were.
This particular stretch was practically cut in half to make way for more popular new tunnels. Today, it sits silent. One track occasionally used for layups (parking of out of service trains), the other looking intact yet dirty and disused for quite some time.
The likelihood of this tunnel ever returning to it’s former glory is pretty much zero.
So here it sits… Marginalized, but not quite forgotten.
