The River Line's Last Conrail Signals - Part 1

Over the years I have reported on the CSX re-signaling efforts on the former Conrail River Line along the west side of the Hudson River. These efforts go back to the early 2000's as CSX looked to increase capacity on the route after its takeover and culminated in the recent re-signaling of CP-SK in Selkirk, NY.  CP-SK was able to hold out as long as it did because it was itself completely re-signaled by Conrail immediately before the CSX/NS split, dropping the need for capital improvement way down on the list. However for those Hudson Valley Conrail fans looking to get signaling fix, two small islands of Conrail era signaling remains. 

Back in the 1960's, the old West Shore route was given a healthy dose of efficiency by the innovators at the  New York Central, changing a double track line into a single track with passing sidings spaced every 10 miles. This budget CTC system featured single block, restricted speed passing sidings about every 10 miles and fit in with the decline in northeast freight traffic, especially after the Penn Central and Conrail was able to divert traffic away from the former NY Central main line and the West Shore Route. However, as intermodal traffic picked up in the 1990s, Conrail found its River Line under capacity as every pass would require a painfully slow restricted speed pull-in.  Therefore it began to signal the sidings and modify the old New York Central small target searchlight signals to support Medium speed diverging routes, generally working south to north.

Just prior to the CSX takeover in 1999, Conrail was largely finished with this project, however for whatever reason the old passing siding between CP-104 and CP-106 was found to be lacking and the siding was expended a little over a mile to the south to a new CP-102 with CP-106 also being completely rebuilt. In the same project,  the siding at the southern end of the line from CP-22 to CP-24 was extended to a new CP-26. In a manner similar to CP-SK, CSX put replacing both these patches of late model Conrail signaling low down on the priority list and today these two sidings and some adjacent intermediate signals are the only remaining Conrail signals on the River Line. Here in Part 1 I will cover the northern island with CP-104, CP-106 and the intermediate at milepost 100.

With CP-106 directly adjacent to US 9W just south of Catskill, NY and CP-102 behind the quaint West Camp, NY post office, both locations are generally accessible and equipped with two Conrail target type color light masts, a 3-lamp Safetran dwarf stack, CorTen weathering steel relay huts and those iconic blue station signs.

The the 1008/1009 automatic signal, distant to CP-102, is just south of the Malden Turnpike grade crossing at River Line milepost 102 and also pretty easily accessible. This one makes use of premium US&S target type color light signals as opposed to the Safetran signals at the two interlockings.

In a future Part 2 I'll throw up some photos of CP-22 and CP-26 the next time I find myself driving to Upstate NY or New England. It's highly likely that CSX will also replace all these signals whenever some manager happens to notice the non-conformity. Moreover, without their presence there would not be much stopping CSX from a wholesale change in signal rules on the River Line from Conrail to Seaboard, so get out there and get your photos of R/*Y* Medium Approach while you still can. 

Last Traditional Signalbox Closes in New Zealand

Word has come down that Wellington A Signalbox has closed. Constructed in 1937 in conjunction with the Hutt Valley 1.5kv DC suburban electrification scheme, Wellington A Box was was not only the last full time staffed signalbox in the Wellington suburban network, but also the last traditional signalbox of any kind in the country (although it's implied that part time signalboxes might still exist). Corner cases aside, this marks the end of a 25 year long transition from a network with numerous staffed signalboxes containing both "power" frames and unit lever CTC panels.

With signaling system essentially in alignment with the American method, New Zealand was a fun house mirror of signaling equipment that was just a little bit different than its North American counterparts. Unfortunately, just like was seen in North America, New Zealand implemented several national railway "investment" schemes that swept away the old cast iron searchlights and signalboxes and replaced them with LED color lights and signaling centres with video display interfaces. I had previously covered two phases of this transition with the closure of PETONE signalbox in 2013 and ADDINGTON signalbox in 2016. Although re-signaling efforts had slowly chipped away at Wellington A signalbox over the years, the terminal interlocking at one of New Zealand's busiest stations was able to hold on in a similar fashion to CNW LAKE ST in Chicago. In another parallel to LAKE ST, Wellington A signalbox contained a fairly large all electric power frame of the Westinghouse Brake and Signal Co "Style L" variety, which is essentially an evolved British pattern US&S Model 14 machine that dispensed with the mechanical locking grid in favor of electric circuit based route locking via the usual US&S pattern locking magnets.

Covered in great detail on the WB&S Co power frame website, Wellington A box was built with three separate Style L frames, a 67-lever console in the center and two 31-lever consoles on either end. Later the left console would be replaced by a unit lever CTC panel. Dave, the webmaster of the now defunct Valley Signals page, provided his own extensive coverage on the final decades of Wellington A Box, now available via Archive.org.

Kiwi Rail was thoughtful enough to post a couple of Youtube videos profiling the signalbox, the Style L frame and the remaining operators that worked it. While the miniature "armstrong" levers look very British, its important to understand that these are essentially US&S style crank levers set vertically and rotated 90 degrees. You can see in the photos and video the familiar spindle type electrical contacts below the levers with the locking magnets out of sight behind. In addition to the official video is another one that seems to have been produced for local media with a bit more detail and external shots.






While I said this was (likely) the last operational traditional signalbox on the NZ rail network, the Keirunga Park miniature railway is signaled from a local signalbox equipped with another WB&S Co Style K power frame donated by New Zealand railways in 1985. To the extent this "counts" is left as an exercise to the reader, but it offers a preservation experience on par to that of HARRIS tower in the United States. Anyway, check out the linked resources before they to go out of service.

Valleysignals.org.nz Fades Into History

While performing research on an upcoming post I regrettable discovered that the excellent Hutt Valley signaling website (aka Valley Signals) has gone offline with the domain, valleysignals.org.nz, now pointing to a reseller. Although focused on the specifics of signaling in Hutt Valley north of Wellington, it provided extensive detail on NZ signaling in general including the change from the relay to solid state era between 2001 and 2013. With photos, signal diagrams and quite a bit of inside information the Web 1.0 era site gave visitors all the necessary information with little fuss.

Originally hosted on Trainweb, it long ago moved to its own hosting and domain. Around a decade ago it backed up my own coverage of PETONE signalbox during its last few months of operation. Along with other web 1.0 websites like Blockstation.net and Mark Beij's signaling site (hosted on the defunct Keystone Crossings), it was easy to assume they would be be online forever. Unfortunately those with enough life experience to self-host websites in the 1990's and early 2000's are rapidly approaching the age where their heirs will be getting the emails about domain name renewal. 

Valley Signals Webmaster in 2013

From what I have gathered, the individual behind Valley Signals, who apparently went by Dave, started the site in 2001 as a way to document all aspects of railroad and railroad signaling history in the Wellington, NZ area.  The site was fully fleshed out over the following three years with regular updates through 2013 when Kiwi Rail implemented a major re-signaling project in the Hutt Valley, wiping out most of the relay based signaling. Unfortunately in a 2019 "site status" blurb, he mentioned having lost all interest in railways as of 2016, but had decided to keep the site up with some additional sections on his more personal interests. By 2023 the domain had lapsed. As we can see from the photo above the owner appeared to be at least in their 70's or 80's as of a decade ago. This unfortunately does not bode well for trying to rescue the site in an official capacity and because their contact info (e-mail) was based on the valleysignals domain, there is no longer a way to reach out.

The webmaster waving to the last train signaled through PETONE signalbox.

The good news is that the Wayback machine seems to have preserved most of the site contents and because the site was so static for so long, there was ample opportunity for it to be scrapped multiple times, so if you get an error for pages on the most recent dates, you can go back to 2013 without loss of content. Using this resource I was able to restore all the links on my PETONE signalbox page. Still, given the Internet Archive's own legal issues I will make an effort to save out as much of the Valley Signals content that I can. Despite the webmaster's assumed passing, if anyone knows what happened to the person or persons behind Valley Signals, please let me know as I might have some options to get a more official mirror back up and running.

DOCK Movable Bridge to Become DOCK Bridge

In 2017 the great DOCK tower closed as a staffed interlocking station after about 80 years of service. However the imposing structure retained one last official duty beyond "employee lounge" and that was housing the controls and auxiliary equipment to work the adjacent three span vertical lift drawbridge situated between the tower and Newark Penn Station.

 

Unfortunately the Passiac River was not the industrial thoroughfare of years past and unlike the nearby PORTAL bridge whose low clearance made it subject to periodic openings for barge traffic, the height of the DOCK draws is sufficient for the dwindling commercial traffic on the waterway.  After not opening a single time in 2024, Amtrak has petitioned the Coast Guard for permission to permanently close the bridge.

While it is unlikely that anything will happen to the bridge, Amtrak will no longer have to maintain the operating equipment, interlocking logic and the mechanisms used to make and break rail and overhead wire continuity.

DOCK draw actually contains three independent movable bridge spans. A large 3-track north span for mostly westbound Amtrak and NJT trains, a 2 track span for PATH rapid transit trains and a single track span for mostly eastbound Amtrak and NJT trains. The PATH span was set at a higher clearance above the river to reduce the number of openings on what was higher frequency rapid transit line.

 

One interesting quirk was the use of standard point machines to work the rail locking mechanisms at least on the PATH tracks. 

Based on the general interlocking layout I would not expect many signals to move, although the eastbound signals on tracks 2 and 3 might be moved across the bridge to resolve possible ACSES positive stop issues.

The fate of the control equipment on the operator's level and the auxiliary equipment, like AC-DC motor-generators, on the cavernous ground floor remains to be seen, however the safe option would be to leave it in place just in case. Numerous lift bridge have been converted to a fixed status with the counterweights left to dangle for many decades with little thought.

The petition requires a 120 day trial period of being "closed" at which point it will be approved or denied. After that there would be no set timeline for Amtrak to make changes so if a signal move looks likely I'll keep you informed.
