This site is dedicated to all things related to this little 11.5 mile gem of a railroad branchline. Begun in 1892, the B&O laid track from MP 8.3 on the Metropolitan Branch to Chevy Chase, MD originally to serve a coal fired power plant of the Chevy Chase & Kensington Electric Rwy. and some other freight customers. Petitioners in Georgetown eventually won their case and the B&O built on down to the bustling port along the Potomac between 1908-1910. The vision that the line might be a link to the southern railroads never materialized. The plan was to build a bridge across the Potomac near Chain Bridge, but the finances of the B&O would utterly prevent this. The line saw varying levels of traffic, eventually succumbing to truck traffic, dying businesses along the line, and a suburban housing explosion. In 1985 the line was formally abandoned and in the early 1990's it was transformed to a rail trail.

Wow what a little gem, thanks for posting this, right up my street :doublethumb
