This aerial photo marked March 1972 captures the entire Claremont Branch. This tour progresses generally west from CSX's Mount Clare Yard on the right to the Pennsylvania Railroad / Amtrak Northeast Corridor on the left.

Black lines trace various railroad alignments; where they lack perpendicular lines, rails existed previously but are no longer extant as of 2015. Note at photo bottom that at photo time Interstate 95 terminated at Caton Avenue. It had not yet been completed through Baltimore and the then-on-the-drawing-board Fort McHenry Tunnel.

Though its labeling suggests a photo date of March 1972, trees appear in full leaf growth so the image was likely recorded earlier, perhaps during summer 1971.

We're looking toward the north end of the Mount Clare Yard (B&O called it Claremont) that is part of the B&O Old Main Line. Originally, the Claremont Branch had curved away to the west (left) in the distance. Beyond that, you can glimpse the southwest end of the track over the Carrolton Viaduct. About a mile further east lies the B&O Railroad Museum in Baltimore. Interstate 95 casts shadows from above.

Though the view is obstructed, with luck while zooming past on I-95 you might spot a westbound train rolling off the Carrollton Viaduct to enter the yard.

Note the gap in the weed growth on the fence just ahead of the train. That's where the Claremont Branch had originally split off before curving sharply around buildings on the left. A 1915 atlas shows the area inside the curve as home to the Greenwald Packing Company.

This view from air captured the Claremont Branch's original alignment, the bright arc near the smokestack.

That's B&O's Carrollton Viaduct at right and Western Maryland track going under B&O.

The reverse view shows the Claremont Branch's original alignment peeling away from the yard at lower right. This photo pre-dates I-95 over the yard.

The revised alignment curves west (right) immediately beyond the buildings at right where one now finds Wilmarco Avenue.

Assorted sidings served industry here, including ones represented by rails-in-concrete near the white vehicle ahead.

Those sidings are more easily seen when looking back from the vehicle location. One of those at this grade crossing with Wilmarco Avenue was repurposed into the newer alignment from the yard. Next, we'll return to the yard.

When Interstate 95 arrived here around 1980, CSX realigned its Claremont Branch connection to share the Mount Clare Yard road entrance from Bernard Drive at left. Westbound trains from Camden Station and Locust Point can enter the yard, approaching the camera, then reverse to exit it via the Claremont Branch.

The realignment left room for a wye that would do away with the need to reverse. It would permit direct access between Camden and what is now Amtrak's Northeast Corridor, which is where this tour is headed. That wye is being considered as part of the Penn-Camden Connector.

Portions of the Claremont Branch rails have been pulled up so this train will not be making the trip to the Northeast Corridor. Trains that had done so (until around 1990) sometimes paused here in the yard.

At the Mount Clare Yard road entrance -- or, in this viewing direction, the exit -- the Claremont Branch crosses Bernard Drive. This Trico crane was dismantling ramps built decades ago to directly connect I-95 and I-70.

Those ramps became useless because environmentalists blocked within Baltimore City the final 5 miles of I-70's 2000+ mile route. Ironically, countless gallons of gasoline are now wasted each year in traffic jams caused by the lack of such a connection. The photo at right illustrates I-70's ignominious eastern terminus as a Park 'N Ride at the Baltimore City line.

We've arrived back at the Claremont Branch's grade crossing near Wilmarco Avenue. The original alignment had curved in from the right before proceeding ahead.

After a brief trackless stretch as we head west, we find rusty check rails that help protect derailed cars from straying too far from the track. They are often used atop bridges, and are also called guard rails and bull rails. These check rails are of the style employed by the Pennsylvania Railroad, suggesting at least this segment of the Claremont Branch was its responsibility. A 1948 map shows most of the Claremont Branch to belong to PRR.

Sure enough, next is a bridge, now being consumed by weeds, trees, and plenty of poison ivy. This bridge spans Wilkens Avenue and former ice ponds of Maidens Choice Creek.

The branch had never been double tracked. Can anyone loan a weed-whacker and saw?

Though patinaed with rust, the bridge supports appear in suitable condition for train service to resume. Of course, engineer crews would need to verify.

From street level, the bridge does not appear to need as much groundskeeping.

Nearby neighborhood stores supply the essentials. If you ever need Harware-Toilet Tissue, Soap Locks, or key food groups, now you know where to find a Convenient Store that can help. Since photo time, this store has closed.

Utility lines parallel the Claremont Branch. Yes, rails are hiding in this overgrowth as seen looking back from Wellesley Street. A dense stand of trees have taken hold behind the photographer, suggesting the track between here and the Northeast Corridor was dismantled some time ago.

The vined Caton Avenue bridge would blend well within Sanctuary in the 1976 Logan's Run movie. We're close to the Northeast Corridor now (unseen on the right).

The Claremont Branch met the Pennsylvania RR / Amtrak in a wye formation near milepost 100 so trains could proceed both east and west along the Northeast Corridor. Amtrak and MARC now keep busy along this stretch where Wilkens Avenue spans overhead. Milleposts are measured from PRR's Broad Street Station in Philadelphia, Pennsylvania,

In the photo above, note the boulder between the end of the train on the right and the equipment box. That boulder resides where the Catonsville Short Line had diverged from the Pennsy. Old aerial photos suggest sufficient track switches had never been installed to permit trains to roll from the Claremont Branch onto the Catonsville Short Line.

All but a few remnants of both legs of the wye were removed around 2010. The Penn-Camden Connector will restore them. In this zoom view, some surviving track segments -- plus beyond them ballast curves or shadows -- mark where the wye had split off.

Looking back from the boulder, note the short pole on the right with a corresponding concrete block for a pole on the left. These may have been associated with the Claremont Branch. The boulder is a former Baltimore City boundary stone.

MARC 33 passes the Loudon Park Substation on the left, another possible reason for the extra poles.

MARC Penn Line trains like this follow what had been the route of the Pennsylvania RR between Baltimore and Washington, DC. MARC Camden Line trains follow B&O's route between those cities, the only route that serves the home stadiums of the Orioles and Ravens. The proposed Penn-Camden Connector would revive the branch and permit Penn Line trains to bring fans to and from the stadiums.

MARC 20 speeds local passengers past tall catenary poles. Note how the poles near the train are located the usual distance from the rails while those ahead are further from the rails. The ones ahead had provided room for the Claremont Branch's now-dismantled westbound wye track.

Now we've moved a bit east, across from what had been the center of the wye; the eastbound leg had extended into the distance on the right. Note the white tank in that direction to the right of the quickly approaching engine. That's now a fixed-location tank, but into at least the 1970s tank cars were picked up and dropped off there by the railroad.

About two seconds later, Washington-bound Amtrak 643 model ACS-64 has obscured much of our view while dead insects similarly challenge the operator.

This aerial photo captured the western end of the Claremont Branch during its active days.
