The Reading Belt Line was built in 1900 to allow trains of black gold from the Anthracite regions of Eastern Pennsylvania to bypass the increasingly congested Reading yard. It was emblematic of a time when advances in industrial technology would allow the rickety 19th century rail network to get upgraded for the age of steel for those wealthy railroads that could afford it. Running from Klapperthal Jct south of the city to Belt Line Jct in the north, today it hosts the vast majority of NS through traffic on the Reading and Harrisburg Lines as they run between eastern markets and Harrisburg.
What caught my interest was the presence of surviving Conrail era signals on the line which have managed to survive several major NS re-signaling projects in recent years. Always wary of "future developments", I booked a weekend with Reading area rail enthusiast Kevin Painter to visit the Conrail signal locations as well as some other Reading area landmarks. Unfortunately the gods were not kind to me and I caught zero NS freights over the entire course of the day. You can still see all the photos I did get here (mirror).
The first stop was CP-TULP where the Reading Line crosses the Tulpehocken Creek via a single track bridge. The entire bridge is within interlocking limits and the interlocking marks the division point where westbound Reading Line trains can head east to Philly or continue west to Harrisburg. First re-signaled by the Reading in the early 1950's as part of a general Reading area CTC project that concentrated control at two new towers, VALLEY JCT and OLEY, much of this territory would be end of life by the dawn of the 21st century and CP-TULP was again re-signaled by Conrail in 1998 or 99, immediately prior to the NS/CSX split. Therefore, as the interlocking hardware is essentially "new enough" it has so far avoided re-replacement. Here we see the eastbound Reading Line signal for eastbound Harrisburg Line traffic adjacent to the Conrail blue station sign.
Although Conrail was known for using "pinch points" instead of a normal
double track crossover to save money, the Reading era single track
bridge over the Tulpehocken Creek was the motivating factor for
CP-TULP's design, not Conrail's frugality. The westbound signals
feature 3 heads due to CP-TULP being back-to-back with CP-VALLEY JCT and
CP-DUNKLE, necessitating the need for R/Y/G Medium Approach Medium.
Although clearly an equilateral turnout, Conrail did not like the concept and designated track 2 as the diverging route.
The milepost 6 intermediate mast signals replaced a pair of Reading era
bracket masts visible from the adjacent PA Route 12. The portion of the
Reading Line between CP-BLANDON and CP-WYOMISSING JCT uses its own zero
based mileage reflecting the history of this route as a bypass.
If there is congestion on the Belt Line or if carloads need to be
handled at Reading Yard, trains may be routed via the slow road through
downtown Reading. CENTER interlocking, established during the 1950's
CTC project, represents the western apex of the old Reading Outer
Station wye where traffic bound for Harrisburg would emerge from the
Reading terminal complex.
Left largely intact from the Reading days,
CP-CENTER was recently re-signaled with the western switch and
interlocking limits relocated to the west to save on grade crossing
logic and allow for a higher speed turnout.
The eastbound signals were also made more descriptive providing for
medium and full speed indications to the Pottsville Branch even though
speeds on both legs of the old Outer Station wye are only 10mph.
The south leg of the Outer Station Wye is represented by CP-WALNUT.
Replaced by Conrail in the late 1990's, new NS signals replaced the
Conrail masts in 2018 or 2019. A major hub of activity during the days
of the Reading railroad, Outer Station
closed in 1969 and was destroyed by fire in 1978. In the early 2000's
the city public works opened a large facility on the site and today much
of the surrounding brownfield has returned to a natural state.
