Signals of the Reading and Northern Lehigh Line

Pennsylvania's Wyoming Valley, today home to the Scranton–Wilkes-Barre metropolitan area, was the West Texas or Saudi Arabia of the 19th century due to its massive reserves of Anthracite coal. A premium product demanding premium prices, anthracite coal was the way that industrializing America kept warm in the water months after the landscape had been stripped bare of trees for firewood. This is how the Wyoming Valley could fund the operations of three major railroads (the Lehigh Valley, Central RR of NJ and Delaware Lackawanna and Western) and similarly explain why those railroads seemed to evaporate without a trace when the world moved on to oil and natural gas.

Perhaps nothing optimized the uniquely American phenomena of direct railroad competition like the LVRR and CNJ, whose main lines were both functionally and in some places literally parallel. In the 1960's the anthracite collapse was well under way and a decade before Conrail, the CNJ had decided to throw in the towel and allow the LVRR to consolidate its operations to Scranton. North of its large yard in Lehighton, PA, the LVRR was able to stitch together a hybrid route, using better aligned portions of the CNJ over the Pocono mountain summit between White Haven and Laurel Run. Later, Conrail would choose to use the CNJ main line between Lehighton and Allentown creating a Frankenstein's monster "Lehigh Line" between NYC, Scranton and NY's Southern Tier. As the region's industry continued to shift, Conrail shoveled off the Lehigh Line north of Lehighton to the upstart Reading and Northern in the 1990's.

All this history is necessary to understand why the signaling on the Lehigh Line portion of the Reading and Northern's main line between Reading and Pittston, looks the way it does. Recently made visible by the series of R&N Iron Horse Rambles and its regular weekend Lehigh Gorge excursion service, the current signaling on the upper Lehigh Line reflect its unique history. In the 2024/2025 time frame I was able to gather enough content to put together a signaling guide covering the old Lehigh Line between Mauch Chunk and Pittston.

We begin at R&N's COAL interlocking, which was built new by them to support the R&N's "Main Line" concept between Reading and Pittston, but also its Lehigh Gorge tourist operations. Using a salvaged lattice cantilever mast, COAL connects what was the old CNJ route to the former LVRR route at the south end of the Lehigh Gorge.

Into the 2000's, Conrail (later NS) owned and operated this portion of the Lehigh Line as a double track Rule 251 main line. Traffic was so light that the southbound track was used bi-directionally with northbound trains needing to get a Form D, while the southbound track had its signal system taken out of service and used for R&M excursions and freights. NS moved first to convert the southbound track to Rule 261 (CTC) operation, with the R&N converting the former northbound track to Rule 261 in the late 2010's. Each track has a single ABS signal location in this line segment, NS at LVRR milepost 126 and the R&N's at its own milepost 124.

A quick note on Mileposts. In the Conrail era the Lehigh Line would alternately use legacy mileposts from the CNJ, LVRR and LVRR Mountain Cutoff. The Reading and Northern switched this to its own mileposts that continues the Reading Company chaining from the old Reading Terminal.  Somehow this has managed to match up with the legacy CNJ mileposts within a few tenths, but LVRR mileposts are off by several miles. I will be using the R&N mileposts for most of this article.
 

CP-M&H JCT marked the transition between double track ABS and single track CTC through the Lehigh Gorge and, starting in the 1990's, the start of the Reading and Northern lease. CP-M&H JCT was re-signaled by Conrail around the time of the lease and has the typical Conrail hallmarks of a CorTen steel relay hut and color tri-light signals. What sets CP-M&H JCT apart is the use of "budget" L&W brand modular signals in the tri-lights. It's entirely possible that the lease arrangement had Conrail responsible for some portion of the signaling system (the interlockings still appear in CR's 1997 signal charts) resulting in signaling that looked Conrail, but with different hardware.

When the R&N lease came into force the arrangement still created a gap in the R&N's conceptual Main Line between Mauch Chunk and CP-M&H JCT where they had to run under Conrail rules and dispatching. When NS finally transferred the northbound track to the R&N in the mid-2000's, they were so thrilled to be in total control that they built a new interlocking back-to-back with CP-M&H JCT named INDEPENDENCE.

The mast is for CP-M&H JCT and the dwarf for INDEPENDENCE.

CP-M&H JCT wasn't an isolated re-signaling as it appears that all of the signaling in the Lehigh Gorge proper was replaced around the time of the lease. This was possibly due to the desire to replace any pole line based system due to the inaccessible nature of the right of way in the Lehigh  Gorge. The new Conrail style signaling again reflected the economic decline of the region with a shift to extra long 3-4 mile signal blocks versus the standard 1-2 mile length. ABS signal locations in the gorge are at R&N milepost 130, 133/134 and 138. The 133/134 location split the Jeddo tunnel for visibility reasons.

134S from behind

It appears that the pole line was retained to supply 440v power to the signal locations, however it is unclear if this supply is still in service.

The end of the 90's re-signaling is at the controlled holdout signal CP-WHITE-HAVEN, which is just a few miles shy of the alignment change from LVRR to CNJ. I do not currently know the status of the CNJ main north of Lehighton prior to 1965, but the re-signaling boundary is surely related to the relative utility of the CNJ signaling versus the LVRR signaling. One possibility could be a post-war investment in CTC by the CNJ to cut costs that exceeded the standard of whatever the LVRR was up to at the same time. 

RBMN CTC Gap Slowly Closes

 In my last RBMN signaling update from a speeder video in the winter of 2022, I noticed that turned signals had appeared in the last gap of dark territory on their Main Line between Hometown, PA and JIM THORPE JCT near Mach Chunk. Well as of the Iron Horse rambles of Summer 2024 the gap has closed ever so slightly with the ABS now ending at the turned Milepos 118S intermediate and the formerly turned 118N intermediate now being an active distant signal for JIM THORPE JCT. Although I didn't get a photo of the 118N, the 118S now bears the "END AUTO BLOCK" sign.

Apart from this I noticed no additional signaling changes on the former Conrail Lehigh Line, although I just now realized that the RBMN built a brand new interlocking on the Lehigh Line between CP-DUPONT and CP-LAUREL HILL in order to place out of service a portion of the second main track there.

The "new" SEIDEL interlocking uses the same 1980's GRS type three lamp housing color light signals that are also in place at CP-DUPONT and some nearby intermediates. Likely in place for well over a decade now, I had always assumed it was a Conrail era interlocking.

Reading and Northern Video Update

 It's been a good while since my last Reading and Northern update and although there's been nothing earth shattering I was recently tipped off to a cheat code when it comes to exploring the generally less accessible northern division between Scranton and Jim Thorpe. With the general collapse of any other interesting signaling in the region I have been been putting additional time and effort into getting photos of the R&N's newly installed CTC signaling between Reading and Jim Thorpe.  However while the R&N inherited some interesting bits of signaling from the Conrail era, most of it reachable either by boat or long hikes along 20 miles of inaccessible right of way in the Lehigh River Gorge. My Plan A was to try and grab a seat on one of the many R&N passenger excursions however the summer 2020 one was cancelled by Covid and the recently announced one in May 2023 quickly sold out. 

However one of my fantastic readers linked me to a speeder enthusiast's Youtube channel that included a 2022 speeder trip from Reading all the way to Pitson Yard north of Scranton, which is pretty much the entire R&N CTC'd main line. This basically provided all the signal status information you need for either fact of existence or for planning more involved photo trips. Part 1 covers Tamaqua through White Haven in a very respectable 90 minutes with part 2 White Haven to Pitson.

If you don't want to spend 3 hours watching the videos the TLDR is between CP-COAL and CP-WHITE HAVEN the LVRR signaling has been replaced by square Safetran CL-10 modules in a target/tri-light configuration. Between White Haven and Glenn Summit is where the LVRR searchlights appear and finally between Glenn Summit and CP-DUPONT is the land of 1980's non-modular GRS traffic lights.

Aside from closing the gap between the Hometown viaduct and Jim Thorpe, I'm not sure how much more the R&N is planning to expand its CTC, but whatever they do I'll be sure to report on it here. Meanwhile I will continue to gather R&N signal photos for additional less current events type posts.

No More Lehigh Valley Signals on the Lehigh Line

Just got back from a road trip and to my disappointment I discovered that the remaining Lehigh Valley RR signals had been removed from the lower half of the Lehigh Line between CP-67 and Bethlehem, PA.  Caught up in this sweep were the former CNJ/Reading interlockings of CP-ALLEN, CP-CANAL and CP-JU (previously re-signaled by Conrail).  

The project had been underway for well over a year and I had taken the opportunity to document as much as I could, however I missed the two LVRR automatic signal locations at MP 71 and MP 74 as when I passed them by last October they did not appear to be under threat.

Of course the most devastating loss will be the classic LVRR Gantryleaver signal at the site of the former Easton, PA station.  This stout structure was in no structural danger and had been upgraded over the years with railings and walkways, but it appears that NS's commitment to its heritage is limited to more PR friendly devices like locomotives :-(

The former CP-RICHARDS was replaced by a new crossover a few miles to the west as once again the block lengths were stretched to reduce the number of signaling locations. Rule 251 was then replaced by 261 between CP-RICHARDS and CP-BETHLEHEM.  

I was also disappointed to have missed documenting CP-JU.  Although the original CJU plant with pneumatic points and signal bridges had been replaced by Conrail, it was nevertheless a great example of Conrail signaling, complete with searchlight dwarfs.

Finally, the odd arrangement between CP-EASTON and CP-PHILLIPSBURG wherein trains crossing the Delaware River could not get an Approach indication.  Signals would only display Clear or Restricting for following movements.  This was possibly due to some previous restriction regarding trains being stopped on the bridge, however NS appears to have remedied the problem and trains can get Approach at both locations.  I should also mention that CP-PHILLIPSBURG had already gotten new Darth Vader signals installed within the last 5 years for...reasons.

This is yet another lesson about not taking things for granted.  If you have the oppurtunity to photo something, do it ASAP, even if you think you'll have time enough to catch them "later".  If you would to see what I was able to document my Lehigh Line Amtrak Autumn Express photos can be found here and my Easton Roadtrip photos cam be found here.

What's Up with the Reading and Northern?

The Reading and Northern has been a rare bright spot in the world of signaling.  A commitment to its Reading heritage has resulted in numerous signaling structures being preserved along with attempts to install "classic" signaling where new signaling is being installed on its mostly unsignaled territory.  The R&N also controls the former Conrail Lehigh Line and for one reason or another has decided not to touch the surviving LVRR signaling along that route.  Still, I am still not completely clear on the full extent of the R&N's signal preservation efforts as hinted at in a number of photos I have come across.

We begin near the town of Mach Chunk where the R&N runs a tourist operation in the Lehigh Gorge.  i have bicycles along the right of way a number of time and I never noticed this cantilever mast and its freshly painted (albeit turned) signals.  Is this a sign of a new interlocking or signaling project?

Pottsville is the location of some preserved Reading signal bridges and a tower.  Both have been out of service for decades, but then I find a photo showing what appears to be a lit Reading US&S three headed signal displaying a restricting indication.  Could be that the photographer is having some fun with Photoshoppe, or it could be another R&N instance of an "island" interlocking designed to eliminate the need for crews to hand throw switches.

Clearly I need to take another field trip to the area, but if anyone has any information (or photos) please let me know.

Bad News with What Could Have Been

Almost all the new I post is of the 'bad" variety, but at the end of today's list I have two examples of the sorts of news we could be having if railroads weren't so slap happy about the scallop shell style Darth Vader signals.

First up it appears that NS has been going after the old Lehigh Line, which is fortunately leased to the Reading and Northern above CP-M&H Junction where NS re-signaling crews can't get to it.  I saw a photo of a train passing under a new southbound cantilever mast at CP-LEHIGHTON, which replaced older Conrail style small target searchlights.

CP-LEHIGHTON was notable for not only a surviving CNJ searchlight on the northbound main track, but also a ghost signal protecting the long removed LVRR main line that ran along the west side of the Lehigh River.  Additional photos can be found here.

NS is also re-signaling CP-253 on the Chicago Line at Port Clinton, OH.  The westbound masts were already given the Darth treatment years ago, but the new job will significantly reduce the length of the interlocking limits by 1000 feet or so.   What I don't get is why the slow speed siding signal is getting upgraded to something with a "straight" route head.  Planned triple-track project?

After dropping new signals all up and down the former Southern main line almost a year ago, NS is taking its time to actually cut them in.

The 32nd St (?) junction complex in Birmingham is probably getting ready to go into its second year as well. 

So would could we be seeing instead of this?  Well not so long ago in Canada new searchlights were still being installed and on right handed masts as well.


Considering LED searchlights are quite popular in the UK, that is one European technology I wouldn't mind importing.

Closer to home the aforementioned Reading and Norther is also installing brand new searchlights and although they are not being used in wider CTC projects, as you can see here the new masts are equipped for that eventuality.
