What drives Arbutus’ History grade

HistoryA character grade: shown, never part of Arbutus’ overall grade.
Few Maryland towns list much on the Register (a typical Maryland town has 0.9 per 10,000 residents, the U.S. 2.4), so Arbutus’ 0.9 sits near the middle of its state (47% of Maryland towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to B+. The pre-1940 share is a Census survey estimate (±3.4 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1896 falls in the same era, so the grade doesn’t depend on which one is used.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.

What stands out about Arbutus’ past
Read from the archive, the National Register and the record. The page puts what stands out first.
The original Relay was an important station on the Baltimore and Ohio Railroad. It was where traffic from Baltimore merged with that from Washington, before continuing west along the railroad's main line towards Wheeling, West Virginia (prior to 1863, Virginia). It was also a key junction for the railroad's telegraph system (the first major system in the country). The Thomas Viaduct is also located in Relay. The bridge is now operated by CSX Transportation, which acquired the B&O in 1987.
