This reverse zoom view shows the increasing elevation of the current tracks since Liberty Mill Road (most distant, about a mile back at Germantown Station) to Germantown Road, then Father Hurley Boulevard (closest).

These dark CPLs were merely resting. The G sign indicates "Grade" and modifies the meaning of the signal lights such that, for example, a train can proceed slowly through a red signal so as to avoid stopping on a hill which might be steep enough to prevent a stopped train from moving again without assistance.

About 2010 CSX swapped out the CPLs for these signals, which are "approach activated" within the block occupied by the train. Since there is no train in the block on the camera's side of the signals, the facing signals are unlit. IMO, they should be lit as a way to warn anyone near the tracks that a train is approaching. The signals in question illuminated only after this locomotive passed them.

yet another improvised Met milepost

The bridge at Little Seneca, one of B&O's earlier such applications of steel, proved a maintenance headache, so in 1927 the railroad realigned a short distance downstream onto this substantial concrete bridge, number 29A, that continues in use now. Claims that during non-leaf season remnants of the steel bridge's stone abutments can be glimpsed through this arch are not true. The stones visible are instead part of flood control.

CSX 47 follows the lead engine. Stock tip: when you see your local railroad renting engines like this, it means demand is high, and therefore it's time to buy the stock. Had you bought CSX shares during October 2014 you would have almost doubled your money in about 2 years.

The realignment mentioned above was B&O's choice to replace this bridge across Little Seneca Creek. The single-track original was a 600-foot look timber monster that survived only about 25 years before this steel structure replaced it in 1896. It would endure only slightly longer.

CSX 623, wearing bc2 paint, along with CSX 8368 and LMS 7925 are about to cruise across the Clarksburg Road bridge at Boyds, Maryland.

The guardrail of the Clarksburg Road bridge appears to be the 1928 vintage original. Also of note is the stairway, an accoutrement unlikely found on a more recent structure. At the top of the stairway had been B&O's second Boyd Station, a frame structure.

Per the station's sign, B&O used the name Boyd rather than Boyds. In 1928 this took the place of the original masonry station that had been sited across the tracks from this one, where the MARC parking lot now is. That masonry station appears within the tour of the original alignment.

This concrete foundation's shape, size, and tracks proximity, plus brick platform join together to say they had been part of Boyd Station. The frame station survived into the 1990s. Unseen on the left, a small waiting shack now serves passengers of MARC trains.

Passenger service that began with B&O is now provided by MARC. Train stations were some of the last places to host pay telephones. Subsequent to the main photo, train-themed bicycle posts were added.

B&O's original brick Boyds station had been where the commuter parking lot now is (behind the photographer).

One of the signs in this photo points to a pedestrian underpass.

If the sign is correct about the 1931 construction date that means this underpass was added after the new Met alignment above had been open a few years.

On the right are two doorways blocked off by railroad ties. Perhaps they once led to stairways up to platforms between the tracks.

The last bits of autumn color were on display during this Thanksgiving weekend afternoon. My research indicates the original and newer Met alignments ran side by side into the shadows ahead before going their separate ways (old to the left, new to the right).

When you see evenly spaced remants perpendicular to the rails like those at upper left, you know they once had supported an interlocking (switch mechanism) operated from a nearby tower. The square hole marks where DS Tower once stood.

The photo of DS Tower at right (credit pending) looks northwest around 1950.

When the railroad no longer needed DS Tower, explosives were used to tip it back into the woods, where various remains can still be found. The concrete foundation survived the demolition. What's in the hole?

Why, the basement of course!

Four soon-to-be-retired CPLs tower over crossovers.

For a few miles west of Boyds, the original and current alignments run in close proximity as evidenced by several bridges and culverts. Here the original stone portion has been repurposed into a road while the rails got a new bridge contiguous. It is not clear to me what year the old right-of-way was disused here, but 1906 (the date stone on Waring Viaduct back at mp 24.7) is a candidate.

This is the all-concrete, newer, inlet side. The bridge is numbered 31A.

New signals guard the crossovers. That's milepost 30 between the signals, while the new equipment box is stenciled mile 30.23. There's some measuring funkiness in this vicinity because the current alignment is about 0.2 miles shorter than the original, but the original milepost locations have been preserved.

You don't see bc2 livery often. CSX painted only 117 engines in this scheme, all model CW60AC.

Since double tracking of the Met was not completed until 1928, the single track passing through a rock cut ahead dates this Buck Lodge photo earlier, but later than the original alignment that is off photo left. This means here B&O abandonded the original alignment for a new single-track alignment, possibly in 1906 when other work was being done. Double track along the second alignment here would not come until later.

The 30.5 at photo botton right matches the milepost, W might indicate the direction of view (West), and 12-6 might represent June 1912.

Adjacent double track, rusty siding rails here display a forging date of May 1927, and connecting segments from 1981 are labelled with the less commonly seen "Chessie System" attribution.

B&O's Bucklodge Station stood on the left until about 1960.

Take a look at the full size image above and tell me which track is getting the green signal, Track 1 (left) or Track 2 (right)?

You knew it: of course it's a trick question, or rather poor positioning of signals. From a distance only one of a pair of signals is visible, and due to the curvature of the rails that signal appears to be controlling Track 2 (right). However as you see at right the real Track 2 signal is instead full red. CSX 72 and CSX 5391 get a breather while an Amtrak passenger train, which will arrive directly, gets the green to go around the freight via Track 1 on the left.

This locomotive unit generates one horsepower, sufficient to carry a rider under the brick and stone dual-arch Bucklodge Branch bridge.

When B&O finished double tracking the Met during the 1920s, many of the old structures needed widening. Here concrete was shaped to mimic the original arch's style.

The extension was added to the south side, the outlet end, of the bridge.
