About Glen Arm

Glen Arm is an unincorporated community in Baltimore County, Maryland, United States. Glen Arm lies along what is now Glen Arm Road, which was once part of Old Harford Road, one of the early routes used for conveying agricultural products from parts of Harford and Baltimore Counties and southern Pennsylvania to the port of Baltimore. Glen Arm was also served until 1958 by the Maryland and Pennsylvania Railroad. In 1921, at the railroad's crossing of Glen Arm Road, what generally is recognized as the nation's first train-actuated railroad crossing signal was installed by the railroad's Superintendent of Signals Charles Adler, Jr. Adler later designed early traffic-actuated traffic lights for the City of Baltimore, and also invented the system of flashing warning lights used on aircraft.Wikipedia

About the Region

Mid-Atlantic

The Mid-Atlantic corridor — New York City south through Philadelphia, Baltimore, and Washington D.C. — is the densest and most economically complex region in the country. Finance and media anchor New York; government, defense, and federal contracting anchor D.C.; healthcare and universities anchor Philadelphia and Baltimore. This makes the region one of the most recession-resistant labor markets in the U.S., though the same fundamentals push housing costs persistently high.

Philadelphia and Baltimore offer substantially lower costs than either New York or D.C. while sitting on the same high-speed rail line, making them increasingly attractive to remote workers and hybrid commuters. The New Jersey and Delaware suburbs fill in between, providing family-oriented communities within commuting range of multiple cities. The region's density means genuine walkability in most urban cores, strong transit infrastructure, and cultural institutions that rival anywhere on earth.
