Bargo once boasted a set of emergency crossovers, as well as a short perway siding. These were all later removed, along with the upper quadrant semaphore signal. An 82 class can be seen in the background with TM72 loaded Tahmoor to Port Kembla coal train.
Thou shall not pass ... if you're heading north, as Amtrak Northeast Regional train 133 crossed over from track 2 to track 1 just north of the Newark, Delaware station, on October 25, 2024.
Note that track 3, which this train would typically use is blocked and out of service for maintenance. Also, to borrow a term from the British, 133 has ACS-64 electric locomotives at both ends; what they would describe as "Top and Tail".

CP 8823 and BNSF 9305 pass under the signal bridge below the stately Dayton's Bluff. After a week of cloudy weather, it was nice to grab anything moving around and get some bright colors. Hard to know if this train is CPKC or BNSF, but I was just happy to see anything really, especially with good timing and a clear Warner Road.
This is the rolling Exmoor early evening landscape as a quick stop off on the way to my main evening shoot location. Just off the A39 near Countisbury, N. Devon, UK.

Closed in April 1998, Indianapolis Union interlocking tower still stood proudly at the east end of the train shed at Union Station. Having controlled movements for named passenger trains such as Knickerbocker, The Penn Texas, Kentuckian, James Whitcomb Riley, The Hoosier, St. Louisan, South Wind, Cardinal and National Limited, along with many others and also freight trains from all of the Indianapolis area roads, it was the largest and busiest in the city. It was also the last active tower, outlasting other locations in the city by at least 15 years.
On this particular day, I my knowledge of the area actually came in handy. My fiend Eric Hendrickson was on a temporary assignment at Avon yard west of the city. Over conversation, the subject of I.U.Tower came up and he had never heard of it. He made a few phone calls to secure access to the building, and we coordinated a day off together for a visit. We saw several trains pass the tower and had a lengthy visit inside to photograph equipment, first for posterity, then with hopes of preserving as much as possible.
Almost an afterthought, Q591 passes westbound among the urban sprawl. On the left is Bankers Life Fieldhouse, the home of the Indiana Pacers, and mixed retail and condos are on the right.

Chicago,IL - Atlanta,GA stack train Q029 snakes its way through Howell Interlocking and under the newly cut in vader signal bridge. The train is making track speed of 25mph and closing in on its destination of Hulsey Yard just east of downtown.

As a photographer, I'm really not a fan of shooting back-lit shots but I do like how this turned out. I couldn't just sit in my car watching as the classic blue & gold New England Central geep passed by. I still had to capture something in my camera. I feel the black and white plus curved track elevation, signal and shadows made it all come together.
a geological formation.
An interlocking spur, also known as an overlapping spur, is one of any number of projecting ridges that extend alternately from the opposite sides of the wall of a young, V-shaped valley down which a river with a winding course flows. Each of these spurs extends laterally into a concave bend of the river such that when viewed either upstream or from overhead, the projecting ridges, which are called spurs, appear to "interlock" or "overlap" in a staggered formation like the teeth of a zipper.[1]
While similar in general appearance, the mechanism behind the formation of interlocking spurs is different from that behind meanders, which arise out of a combination of lateral erosion and deposition. Interlocking spurs are formed as either a river or stream cuts its valley into local bedrock. As it entrenches its valley, it preferentially follows and erodes zones of weaknesses within the bedrock that typically consist of intersecting sets of joints. This process creates a zig-zagging fluvial valley that "interlock" or "overlap" in a staggered manner.
Almost buried amongst the ballast between tracks 3 and 4 west of Gallitzin. This signal governs eastward movements on track 4. Track 4 is rarely used for eastward trains so I guess Pennsy figured this dwarf was good enough. I still wonder what they did after an inch or two of snow.
SIR #448 emerges out of St. George Tunnel with a four-car set of R44s rolling through the B&O-style CPLs at SNX (Slosson) interlocking on a drab Saturday evening on Staten Island with Lower Manhattan and 1WTC visible on the top right.
The SIR is the most interesting of all the lines operated by the NYCT with its own unique operations and history. Opened in 1860 on the island's east shore and reorganized as the Staten Island Rapid Transit in the 1880s, the SIRT was historically owned by the Baltimore and Ohio which financed its expansion into New Jersey via a bridge over the Arthur Kill Strait to a connection with the CNJ at Cranford. By 1900, the SIRT was a wholly owned B&O subsidiary isolated from the rest of the system and reached by trackage rights over Reading and Jersey Central east of Philadelphia. The B&O electrified the SIRT in 1925 taking delivery of brand-new ME-1s built by Standard Steel for rapid transit operation. Construction began on a tunnel under Lower New York Bay to integrate the SIRT with the rest of the New York transit system; the project was never completed.
Service ended between St. George and Arlington on the island's north shore in 1953. The B&O handed over the remaining rapid transit operations to SIRTOA, a subsidiary of MTA, in 1971, and Chessie continued freight operations on the island until it sold the railroad in 1985. By 1991, freight traffic east of Arlington was permanently finished, and the railroad was abandoned west of St. George severing it from the rest of the U.S. rail network.
A lasting legacy of the B&O on Staten Island is the continued use of B&O signal aspects on the SIR. The B&O installed color-position lights on the SIRT in 1924 making it one of the first lines on the entire B&O system with the classic CPLs that we know and love. Originally installed for ABS operation, the CPLs on the SIR are configured for ATC and cab signals. Although most of the original B&O-era masts have been removed (the ones you see here at SNX are MTA-era masts), a number of GRS-built dwarves remain scattered across the line.
Last but not least, SIR operates the oldest cars in revenue service on the New York transit system since the retirement of the R32s in 2022. The R44s in service on the SIR date back to 1973 when the MTA ordered a dedicated fleet of R44s to replace the B&O-era ME-1s that have been operating on the SIR since the 1920s. In addition to the 278 cars built for the NYCT B Division, 64 R44s were built by the St. Louis Car Company to FRA standards for service on Staten Island, the final pieces of rolling stock built by the company before its dissolution. 12 of these R44s were initially sent to the B Division before being reassigned to the SIR in the mid-1980s. Today, 57 R44s remain in active service on the SIR and the last R44s on the B Division were retired in 2010. The remaining R44s on Staten Island will be replaced by the R211S in the near future.
This is one of Birmingham's finest architectural landmarks, The Cube. It's a very unusual design, looking like a complex interlocking puzzle that's been half finished. You can see both the exterior and the interior at the same time.
At the moment it houses Harvey Nichols, shops and a number of excellent restaurants. It's situated right next to the canal so makes for quite an interesting visit.
Waiting to get talked by a bad signal at the ATN interlocking in Attalla, the regal 4270 poses for a roster shot on the point of a deadhead office car move to Birmingham in the spring of 2014. These sure were nice when they were around weren't they? But obviously the cult of "maximizing shareholder value" decrees that nice things can't be had.
