Baltimore & Ohio purchased the second 300 horsepower Diesel-electric Box Cab locomotive built on ALCO Order # S1484 as their Road #1.  It was assigned ALCO Builders #65980 and General Electric Builders #9682.  The above Builders image lettered over the primer paint for the photographer offers a good view of the body plates curving over the roof line (beginning with ALCO Order # S1532 the entire roof panel curved over the body plates).  This view also shows the guy-wire running between the two "Squat Pot" style exhaust system stacks... which is not always visable in images of the first four 300 horsepower AGEIR Diesel-electrics.  Note: This unit has its lettering for #1 and #2 ends, as well as the "A" and "B" sides, overlayed in reverse of all other AGEIR 300 horsepower locomotives.  Prior to delivery to the customer this unit received a coat of gloss paint and a small "OE" was overlayed beneath the "E" in "BALTIMORE" indicating it was an Oil-electric locomotive (the only AGEIR unit so marked). B&O #1 went into service at the West 26th Street Yard in Manhattan New York on December 26, 1925... As B&O Class DE... Reclassified as B&O DE-1 circa 1940... Renumbered #195 circa 1942 and then became B&O Class DS-1a... Received the updated roof exhaust system, uniquely modified roof vents, an "F" above the numeral "2" to indicate the front end... A new bell removed to its unique "B" side, and running lights along the lower sides... This unit became Road #8000 circa 1957 and reclassified again as B&O Class SA-1...
