A little bit more information on that location please. I have no idea where that occurred.
The location is in my post. It occurred in 2014.
The location is several miles due north from Baltimore’s Inner Harbor and central business district in the neighborhood known as “Charles Village” that includes Johns Hopkins University campus and accessory properties. Underneath the area is the notorious 25th Street train tunnel that was built decades ago with a nasty zig-zag jog that will eventually bring about a structural collapse. The tunnel carries both freight and AMTRAK traffic. I became aware of the problem back in the mid ‘70’s when one of my economics professors pointed to the strategic value of that piece of rail infrastructure and how its collapse and interruption of service could be construed as a national security emergency. Elected officials of both parties have kicked this can down the road for decades and at some time the piper will need to be compensated.
