keywords: description:A blog devoted to explaining the ins and outs of North American railroad signaling, past, present and future. This blog seeks to preserve through photo documentation the great diversity and technical ingenuity of 20th century signaling and interlocking hardware and technology. Related topics cover interlocking towers and railroad communications infrastructure.
Note, due to a web hosting failure some of the photos and links may be unavailable.
I recently completed a trip on Amtrak's Vermonter all the way to White River Junction, which covers all of the signaling on the route. The Vermonter passes through three signaling regions each with their own unique features, the Amtrak Springfield Line, the Boston and Maine CT River Line and the New Englande Central main line.
HAYDEN interlocking northbound. Start of Rule 261 territory.
The Amtrak Springfield Line has made headlines with a recent 110mph upgrade programme and support of the Hartford Commuter Rail line. This involved restoration of the double track south of Hartford and Rule 562 signaling (cab signals w/o wayside signals). However one might not know that the Rule 562 only extends to HAYDEN interlocking about 6 miles north of Hartford where beyond that trains still run under Rule 261/CSS.
At the Springfield the signaling is much the same since I was last there, but I can confirm that the USS 3 lamp modular and N-2 dwarfs are still in place at SPRING interlocking. On the former Conrail Boston Line, CSX has indeed replaced all of the SA searchlight dwarfs at CP-98 with Unilens dwarfs. CP-97 was previously re-signaled with 3 and 4 stack Safetran modular dwarfs.
On the CT River Main Line, which was rebuilt and re-signaled around 2014, standard modern Guilford signaling applies with 3-head home signals and offset heads on two head intermediate signals. Single Green clear is in use as opposed to double green. The one exception is at the junction with the east-west freight main line at CPF-385 where the Freight Main Line signals remain BM searchlights.
Budget bracket mast at Putney.On the New Englande Central part of the line things get a bit odd. Leaving the CT River Main and its CTC at East Northfield, the line is run under TWC through Brattleboro to the siding at Putney where CTC begins. North of Putney all controlled siding and diamond crossing interlockings are equipped with searchlight signals except for the south end of the Putney siding that has Vader type color lights and a strange budget southbound bracket bast. Much of the block signaling south of Windsor is still searchlight, but the blocks seem very long with some stretching the entire distance between sidings with a single direction distant mast. North of Windsor the CTC was a recent TWC upgrade with color light masts and what felt like 3 mile blocks.
TLDR the important thing is the searchlight interlockings on the NECR. Safe from the Guilford sale to CSX, but still targets for potential infrastructure spending. If you are in the area, check them out and take photos.
While I don't have specific details, NS has reportedly withdrawn most of its recently planned signal abandonments, including the former DH main line to Sunbury. Not sure if there was regulatory pushback or the recent supply chain crisis made NS thing twice about permanent capacity reductions. Unfortunately NS can't let us have nice things and an eagle eyed viewer spotted new NS masts all lined up by the Reading and Northern yard in Pittston on the former DH at the 6:50 mark in the Youtube video below. Looks like I won't be canceling my Scranton trip after all.
In other Philly news the Ersatz LW brand PRR pedestal signals seen in SEPTA's BROAD interlocking complex have migrated to Amtrak's PENN interlocking on the north side. I wasn't able to get a photo at this point, but I'll try in the future. In other news PENN interlocking was down for at least 3 weeks following Hurricane Ida with all points immobilized and all signals set to Stop and Proceed.
Operations were running as follows. Northbounds on 4, Southbounds on 5. Harrisburg Line Inbound lined to 9, Harrisburg Line Outbound lined to 7. NJTs Keystones running via No. 3 Berry, so it looks like ZOO tower got to save the day
