Belorussian Signal Sabotage

After some initial reports back in early March, it has been more extensively reported since the Russian withdraw from the northern from that Belorussian railway workers and anti-Russian activists had been conducting extensive sabotage operations on Russian supply trains transiting their county with specific focus on the signal system as a method of causing delays without causing death or injury. 

In a previous post covering the nature of ex-Soviet railway signaling I mentioned that the rail network uses a very strongly "station based" interlocking system.  This means that most major stations (think any large community with more than 1000 residents or so) will have crossovers and multiple siding tracks as well as industrial leads and possible junctions.  Between these station interlockings are simple automatic block signals, either single or bi-directional.  The following Belorussian cab ride video shows off the system well along with what appears to be a voice enunciated cab signal system?

Anyway, most of the articles implied that the signal attacks were occurring against undefended ABS signal locations away from prying eyes.  While this would certainly cause some delays, the simple nature of the signaling involved could likely be repaired quickly or worked around with absolute block operation.  The juicer targets of interlocking relay rooms appear to be a much tougher nut to crack as unlike North American interlockings, the location of the central instrument houses is hard to determine as they are not obvious from the cab.  This implies they are in the station or one of the station's outbuildings, which would be far harder to sabotage due to the presence of the public, security personnel, railway staff or CCTV monitoring. The article even goes on to say that the attacks became harder to pull off as local security forces were put on notice.

Because of the old school nature of the signaling, most of the setup would be immune from cyberattacks with the possible exception of any CTC system that might use computer aided dispatch or public networks for communication.

PATH - Still Full of Hot Air

 Although The PATH has stood up a CBTC solution to increase capacity and fulfill its PTC requirement as a railroad, they still maintain a reserve system of wayside equipment that follows their historic pattern of signaling and moreover the PATH remains committed to the use of pneumatic point machines and trip stops.  The Path Guy captured this newly installed US&S pneumatic trip stop at Journal Square that was supporting a platform extension project. The PATH is likely the last operator to continue to install this type of equipment.

2022 Hudson Valley News

My 2022 road trip up the Hudson River valley uncovered several more newsworthy elements than I had encountered in 2021.  The first and foremost of these is that Amtrak has likely completed its refresh of signaling at Hudson Line interlockings with the anticipation of eventual Rule 562 operation.  Although no 'C lamps have been fitted, the Conrail era searchlight signals have been replaced by Safetran modules LED target signals.  At CP-103 these are in new masts at the same location and at CP-114 they have been mounted on the legacy tubular cantilever masts.  In 2021 footings for new signals were in place at CP-94, likely spelling the doom of the bracket mast there. I do not have information about the signals at CP-124 or CP-125.

CP-114

CP-103

At intermediate signal locations the searchlights are still in place and little/no work has been started to install solid state "signal indication point" huts.

In the Mechanicville, NY area, the last gasp of Canadian searchlights are still in place at CPF-470 and adjacent interlockings.  These use a custom housing to hold what are probably railroad-stock searchlight mechanisms.

I also noticed that the entrance signals to the former Boston and Main / Guilford Rail System Freight Main Line at CPF-467 was protected by GE branded signal heads that were a thing due to their takeover of Harmon Electronics. This is fitting given GE's presence in the area.

 

The former NY Central XO tower in Mechanicville has been taken over by the local Chamber of Commerce and someone is building a model railroad layout in the former opeator's level.

Finally I can confirm that the ancient searchlight mast on the former D&H Colonie Sub in Cohoes, NY has been replaced by a CP style Vader mast about a quarter mile to the north of the old location.

Well that's all the news from upstate.  Not great, but not terrible.

WB Tower Relocated!

A little over a year ago I reported on the fate of WB Tower in Brunswick, Maryland.  The wooden B&O railroad tower was constructed in 1910 and closed in late 2011.  Despite plans to preserve the structure it sat empty on CSX property near the Brunswick MARC Train station for over a decade, becoming increasingly insecure and at risk of being set alight by vandals or transients.  

 

Well for once I have some good news to report.  A $15,000 state grant has allowed for the tower's relocation about 100 feet northward on city-owned property where proper restoration can take place.  It will likely be associated with the Brunswick History Museum that already hosts a number of artifacts from the tower as well as a model railroad display. While the relocation will disrupt the tower's historical context, it is a better alternative to fire or demolition.
