At the "waistline" of Ivy City, CSX coal empties are traversing the ex-B&O bridge to the Metropolitan Subdivision. This bridges dates to the early 1900s.

Link: ~1950

This sign under the 9th Street bridge reveals where along the wye CSX places the boundary between the Cap and Met: for eastbound trains "End Metropolitan Subdivision BA M.P. - 1.0, Begin Capital Subdivision M.P. BAA - 37.2".

Since photo time, CSX replaced the CPL signal in the photo with one of its newer design.

Prior to Washington Terminal, B&O's alignment crossed what is now the quasi-traffic circle where New York Avenue and Montana Avenue meet, then continued SW along what became West Virginia Avenue.

As depicted by the double-tracked rail line that extends to the bottom of the image, this 1907 map captures that original alignment, before it was pulled up in favor of the then-new Ivy City, Washington Terminal route north of it. Railroad alignments are all too delible.

Continuing into Washington via West Virginia Avenue yields little evidence the railroad had once been here. I had hoped to find one of B&O's stone mile markers surviving in someone's front yard, but no such luck. Mile marker 37 would have been at the Mt. Olivet Road intersection seen here. On this side of Mt. Olivet Road, on the left, an 1878 GM Hopkins map shows a B&O station. Beyond Mt. Olivet Road on the left, B&O had a small yard, where 11th Place NE now follows the southeastern limit of that yard.

The same markerless situation exists at I and 5th Streets NE. This had been mile 38. From here the original route curved southwest (left) as it made its way about a mile into the distance to B&O's station at New Jersey Avenue and C Street.

Before that station opened in 1851, B&O had only a small station it converted from a boardinghouse at Pennsylvania Avenue and 2nd Street NW (presently near the Capitol Reflecting Pool). All traces of both stations are long gone.

Back along the active route...

The signals facing this direction are of ordinary Pennsylvania RR style, but those opposite are B&O-style CPLs custom crafted from PRR signal parts (view at left courtesy Todd Sestero). This interesting, perhaps unique, combination arose from the shared route to Union Station. Though the two closest tracks are ex-PRR, now Amtrak, MARC trains are sometimes switched onto them to facilitate access to all passenger platforms at Union Station.

Note also there are 2 tracks under the signals, but the signals are shifted to one side rather than being back to back. This was a common PRR practice ostensibly to make the signals more visually associated with their corresponding track. That's the 9th Street bridge in the background.

The Penn Line and Cap Sub lead to the three nearest tracks. The others follow from behind the photographer at Amtrak's Coach Yard at Ivy City, CSX's Metropolitan Sub, and DC Metro's Red Line. Note the verdigrised ground wires attached to the road's fence, perhaps needed due to the proximity of catenary. B&O's C Tower stood near the green patch of grass across the tracks.

B&O oversaw its traffic via C Tower. The tower was removed during the 1970s to create room for Metro.

The western trackside provides the first glimpse of the Capitol. On the signal bridge at left note the small CPLs, Union Station Terminal's own variant of the B&O and PRR editions.

On the right is Metro's NoMa-Gallaudet U stop, the system's first infill station; NoMa = North of Massachusetts Avenue. The distant tall structures this side of the Capitol belong to Union Station.

Now we're looking north with Union Station behind. The tracks were built on an embankment, and most city streets, like M Street ahead, cross under.

Underneath is a combination of stone, steel, and modern concrete.

What happens when you snap a photo with a disposable film camera (remember those?) through the window of a Metro train? You get a poor quality picture. K Tower had directed all train movement at Washington Terminal, but is being phased out in favor of centralized train control from Philadelphia.

Approaching Union Station from the north, as this tour does, H Street is the last street to cross under/over the tracks. During the 1970s this underpass was sealed after the 6-lane H Street bridge was built over the tracks.

The Esso gasoline station at left puts the photo date before 1973 by which time in the United States Esso had been rebranded Exxon; in most other parts of the world it remains Esso. On the right a Railway Express Agency will-call office has yet to see the early 1960s rebranding as REA Express. To support World War I efforts, during 1917 the United States Railroad Administration forced a marriage of seven package transport companies to form the American Railway Express Angency, later the Railway Express Agency. The largest piece of REA came from the company that today is American Express. REA shuttered during 1975.

This photo predates the double-striping of the divider between opposing lanes of traffic. During the early 1970s most US cities converted from a single-white or single-yellow center stripe to the double-yellow specified by the Manual on Uniform Traffic Control Devices. It's an anachronism for which to watch in movies depicting that time period.

That's the H Street bridge at botton, and K Tower near photo center.

The early 21st century has witnessed a building boom around Union Station to compete with that from 100 years earlier when the station first opened. You might notice no building reaches especially high. That is due to a 1910 District of Columbia law that limits height relative to the width of the street on which the building fronts.

Developers sought to purchase the air rights here in order to build over the tracks, then covid hit and the demand for office space plummeted.

Tough to believe this complex track layout is simpler than it was 100 years ago... one of the old photos below was snapped from roughly the same location.

Diesel engines like this MARC Motive Power MP36PH-3C unit can depart Union Station and follow any of three commuter routes, the Brunswick, Camden, or Penn Line. That is expected to change for the Penn Line when Baltimore's Frederick Douglass tunnel opens and bans the diesels.

Awaiting in the bowels of Union Station for homeward bound, weary commuters are several MARC trains parked nose to tail. This is MARC locomotive 57 pointing the way to the Maryland suburbs.

Sunlight sneaks in where H Street does not cast a shadow. Since multiple trains wait on a given track, to help passengeres identify their desired train, overhead signage includes both a track number and location letter.

Sixty-three Kawasaki-built two-level cars like this one of MARC III type entered service around 2000. MARC added another 54 MultiLevel cars from Bombadier around 2015. Multiple-level cars carry more passengers, but people riding on the top level are more subject to side-to-side car sway.

During January 1953, Pennsylvania RR's runaway "Federal Express" train roared through here and rammed into Union Station, just days before crowds were expected for a Presidential inauguration.

Single-level MARC II passenger cars date to the 1980s and look like this inside. All seats face their respective car end, so half face this way, half the other. Emergency information is on the card at each seatback.

This car is for Democrats only; Republican cars are upholstered red. Independents must ride on the roof. Instead, I trust everyone thankfully realizes all MARC cars accept all passengers regardless of political leaning, agenda, or otherwise.

This disused elevated spur at First and G Streets had connected Union Station (right) with the Government Printing Office (left), now Government Publishing Office. Paper by the trainload could be delivered directly into the GPO without any street running.

This is the view inside Union Station. The main entrance in is on the right side, with ticketing and trains to the left. Perhaps the honeycomb ceiling design found here served as the inspiration for that in DC Metro subway stations.

Union Station in Washington, DC is the end of the line for B&O's Washington Branch. Had this photo been snapped 150 years earlier, B&O's stone twin arch bridge over a Tiber Creek tributary would have been visible near the base of the future flagpoles. Tiber Creek has been sequestered below the west side of the yard behind Union Station.

After years of neglect, during the 1980s the station was restored to its original glory. Fortunately, the grand structure was recognized for its place in history before it could be demolished and replaced. This was where the Pennsylvania Railroad, Baltimore and Ohio Railroad, Southern Railway and others met to exchange passengers in the heyday of rail travel. These days, it remains an important station for train travel.

B&O's first Washington station was a converted house at the northwest quadrant of Pennsylvania Avenue and 2nd Street NW. Sixteen years later (1851), Washington received a second B&O station, this one with a clock tower. It's the distant portion here, with "B&O" in place of the clock faces. Washington's swampy streets were elevated after the Civil War, leaving that portion of the station below grade. So, in 1889 B&O added a street-level wing which is the nearer structure in this view. Punctuation mavens of that era insisted upon a period at the end of labels. A New Jersey Avenue streetcar blurs at the left edge.

Few photos from this angle survive to illustrate the relative location of the train shed (right). The panel below offers a better view of the main entrances.

This station stood at New Jersey Avenue and C Street, about a half-mile southwest of the future Union Station. It endured until Union Station opened in 1908. Harwood's Impossible Challenge II has station photos from other decades on pages 150 and 151.
