The JFX has been on the left since the 1950s, and NA Tower was still in use
in 1977, while at top a pre-Magnum Tom Selleck hawks cigs.
On the right the thumb protruding from North Avenue marks the east portal
of the West Baltimore tunnel opened by the Baltimore & Potomac (B&P) Railroad
during 1873. The B&P Tunnel has three sections -- this one named for nearby
John Street -- all of which were inherited by the Pennsylvania Railroad and are
now part of Amtrak's Northeast Corridor. On average a train rumbles through
every 10 minutes, most of which are Amtrak and MARC passenger trains, plus a
few Norfolk Southern freights. The old tunnel has become an operational
bottleneck due to limiting height, curves, and grade.
If you look closely at the "thumb" you'll see a smaller stone arch is contained
within a larger one. The smaller is the actual B&P tunnel while the larger arch
redirects the weight of North Avenue around it.
Like the other railroads, the B&P / Pennsy received two tunnels under
North Avenue. The other is now at photo top, its eastern portal buried by JFX
construction not far from the Selleck billboard, disused so long it is all
but forgotten; you will find no other mention of it online.
