As reported by The Baltimore Sun 15 years ago already:
Residents along Baltimore’s 26th Street have watched their sidewalk sink 6 feet as the earth has eroded around the railroad tracks that snake through their daily comings and goings. Iron rails and a concrete wall have collapsed, leaving gaping holes in the residents’ protection from a 30-foot drop onto the CSX train tracks.
I say 30 years because that’s a 15 year old article. The recent news article and video are available here.
