It had been years since I visited the infamous site in Silver Spring, Maryland where outbound Amtrak 29, the "Capitol Limited," had collided with inbound MARC #286 during a snowy afternoon rush on February 16, 1996. Eleven people died in that collision, three MARC employees and eight MARC passengers. The MARC crew, apparently inattentive, ran a stop signal at Georgetown Junction just as Amtrak 29 was crossing from track 1 to 2 to avoid a stopped K951 ahead. MARC 286 collided with the nose of the lead Amtrak engine, which raked down the side of the MARC cab-control car. The rest is a horror story that's best read in the Washington Post, or better, the NTSB report, available on their Website.
The track that ran from the Junction down to Georgetown, D.C., i.e. the 11-mile-long Georgetown Subdivision, was pulled up several years ago and has been made into a hiking and biking trail. What remains of the original track is 0.3 miles long. It runs from the Junction switch to an industrial area near Kansas Avenue.
Those were the trains I saw. Now, let's look at what remains of the old track down to Georgetown, now called the "Georgetown Industrial Track" by CSX. First, here's an east-facing telephoto view of the interlocking at BA8.3 (CSX Metropolitan Sub). That's the 16th Street highway bridge in the background. The Georgetown Branch switch tied in here at the time of the 1996 collision:
Today, the switch is west of the above location by 150-200 yards (my guess), and can be seen here, camera still facing east. The bridge, a single-lane affair, carries Talbot Avenue left (north) to Grace Church Road. Note the dwarf signal, not illuminated, and the unusual derailer (?):
