Like any self-respecting railroad, the Western Maryland had its own style
Some WM signals in the area remained in use into the 2000s, but since then
new-owner CSX has been on a signal standardization spree, tearing out these old
designs just as it has done to the B&O's distinctive CPL signals. The example
seen here, not in operating condition, is the last standing in the area.
Along former B&O trackage CSX replaced the CPLs with an in-line color light
signal variety, however it has not installed such replacements along this
ex-WM line, at least not within Baltimore City. Instead the
line is currently unsignalled.
