East Deerfield West: Providence & Worcester 2009 leads the Plainville Job.

In 1982, Boston & Maine bought several routes in Massachusetts and Connecticut from Conrail. Among these were lines clustered around Plainville, Connecticut, accessed via trackage rights over Amtrak’s Springfield-New Haven Line.

Today, Amtrak’s route requires advanced signaling on leading locomotives and only a handful of Pan Am’s engines are so equipped. As a result, Pan Am sometimes operates a borrowed Providence & Worcester engine on its East Deerfield to Plainville freight.

As of last week, Pan Am’s EDPL was still operating on a daylight schedule, however with increased Springfield-New Haven passenger services to commence in June, this operation may become nocturnal.

I made these views from the old McClelland Farm Road bridge, a vantage point that will soon be gone when the new bridge opens.

Evening Sun, Southward Freight and a Signal Lesson.

Two weeks ago, my friend Tim and I made photos of Pan Am Railway’s EDPL crossing the Connecticut River at Holyoke, Massachusetts.

A short history: Back in 1982, Conrail spun off some New England routes, including a group of former New Haven Railroad lines in Connecticut. Providence & Worcester and Boston & Maine were among the lines that picked up former Conrail routes.

A vestige of this acquisition, is Pan Am Railway’s (which operates the old Boston & Maine) East Deerfield, Massachusetts to Plainville, Connecticut freight.

Since this Pan Am freight works over Amtrak’s cab signal equipped Springfield-Hartford-New Haven line, the leading locomotive must be fitted with cab signal equipment on that portion of the run.

Since Pan Am only has a few locomotives so fitted (including MEC 352 seen trailing in this view), so today’s train was led by (leased or borrowed?) Providence & Worcester GP38-2 2009 that has the necessary cab signaling (installed for use on P&W’s North East Corridor freight assignments.)

This has been a common occurrence in recent years. Significantly, P&W has been acquired by the Genesee & Wyoming family, and it will be interesting to see how much longer locomotives will operate in the older P&W livery.

For the record: this photo was made on former Boston & Maine trackage, which is not cab-signal equipped. (Cab signal territory will begin about a dozen miles to the south of this location, once on Amtrak trackage)

Palmer, Massachusetts, ‘CP83’ on Friday evening, May 31, 2013.

 

The “C” Light is Lit.

Going back to at least the 1980s, a group of us would convene in Palmer on Friday evenings. It used to be that after closing Tucker’s Hobbies on Fridays, Bob Buck would come down for dinner along with customers and friends from the store. Afterwards, we’d head over to ‘the station’ to watch the railroad.

I recall seeing Central Vermont’s old Alco RS-11s on sultry summer evenings, belching clouds of exhaust and sparks, while we waiting for the parade of westward Conrail trailvans (intermodal piggy-back trains); TV-5, TV-13, and etc. Back in the day, I’d make night shots with my Leica 3A. That seems like a long time ago.

This past Friday, a group of us convened at the usual spot; Doug and Janet Moore, Bill Keay, Rich Reed and myself. After a few trains, Doug and Janet were the ‘heroes’ as Bob would have called them; they headed home and a little while later the signals at CP83 lit up. To my astonishment, the ‘C’ light was flashing (the small lunar-white light between the main signal heads). I rushed for my cameras . . .

The signals at CP83 are approach-lit. So, when the signals light, it means that something (usually a train) has shunted the circuit.  Among other things, CSX’s CP83 governs the switch at the west end of a controlled siding that begins at CP79 (about four miles to the east). When the signals light with a high green, it means a westward train has been cleared to continue past CP83.

Conrail installed the present signaling system back in 1986 when it converted the Boston & Albany route from directional double track under Automatic Block Signal rule 251 ( ‘signal indication will be the authority for trains to operate with the current of traffic’) to a largely single main track system with controlled sidings and governed by Centralized Traffic Control-style signals with cab signaling.

As a result there are now only wayside signals at dispatcher control points such as CP83. CSX assumed operations from Conrail 14 years ago.

It’s rare, but occasionally a locomotive suffers a cab-signal failure, or a locomotive that isn’t cab signal equipped leads a train. There is a provision with the signal system using the ‘C’ light, to allow a dispatcher to authorize a train to proceed without operative cab signal.

CSX rule CR-1280A names the ‘C’ light aspect as ‘Clear to Next Interlocking’. This gives the train permission to proceed the full distance to the next block ‘approaching next home signal prepared to stop’.

Why am I going into such specific operational details? Because, I’m fascinated by signals, but also in the 27 years since Conrail installed this signal system I’ve only witnessed a ‘C’ light lit, three times. And, I’d never before seen the C-light lit at CP83. I’ve been to CP83 more times that I can count, so for me, that is a really unusual event. (I saw a shooting star that night too, but those are common by comparison!)

Fortunately, I had cameras handy, and, perhaps more to the point, I had my dad’s Gitzo tripod, which made this sequence of images possible. (Other wise I would have trying to balance the camera with stacks of coins on the roof of my Golf, but, we’ll save that for another event . . .)

I just wish that Bob Buck could have been there with us to watch the train pass. He would have enjoyed that.
