Larry, just my physical location probably means it's impossible. If that ain't the nail in the coffin, my tech prowess is.

Why is a "penalty brake" called that? Does someone actually get in trouble?

It's called that in ATS (automatic train stop) or ATC (automatic train control) because the system is designed to produce a full stop, sometimes followed by a consequence like a time delay or requiring the conductor to unlock the system, before the train can proceed.

it would be possible to design a system either for train control or vigilance that automatically applies only proportional braking, from which the engineer could recover even after having failed to 'forestall' triggering a commanded brake application.  Very few of the commercially-marketed  systems worked that way.

As the system only sets the brakes when some 'unsafe' action has occurred, you can bet there are "consequences" for having triggered it...

Larry, just my physical location probably means it's impossible. If that ain't the nail in the coffin, my tech prowess is.

If someone has set up a railfan ATCS server for the area that interests you it may be possible to access it everywhere.  There was a period when I could watch the Deshler, OH feed from here in NY.

There used to be an ATCS group on Yahoo, but I believe that has moved elsewhere.

So where does one dispatcher end and the other begin? If a train is eastbound between Harrisburg and Reading, at what point does the Harrisburg East dispatcher stop and whoever runs the Reading yard begin?

Thats what I did. I had to watch a few youtube videos to get my downloads to work right, and even after that I had to change some stuff.

Someone familiar with the line will have to answer that, unless you can find a recent copy of the Employee Time Table.

That you mention "yard" might be important, as a DS may control the main through the yard, while the yard has its own dispatcher or equivalent.  I believe that's how the IM yard at North Baltimore (CSX) works.

I don't know the NS territory.

On CSX Dispatcher's territories begin and end at designated Control Points that are identified in the ETT.  A individual Control Point 'belongs' to one Dispatcher and one Dispatcher alone.  Adjoining Dispatchers communicate among themselves as to what track(s) train(s) should be operated on or if a train should be held back from the designated Control Point for some reason.  The Dispatcher's will provide switch and signal blocking for each other when necessary for the safety of Signal or MofW personnel as required by the rules.

From what I can gather, the Reading yards are still in Harrisburg East's territory, but there is a separate radio channel for the yard, which makes sense. Both East Penn and Reading & Northern tie in at that yard as well. Not sure what channel they would use.

That would depend on the arrangement there.

If each has their own portion of the yard (one or two tracks where they interchange, f'rinstance), they may just stay on their own channel(s).

If they need to interface with the yardmaster, they'll probably go over to that channel.

At Utica, NY, f'rinstance (CSX & MA&N), CSX stays on their road channel when they make pick-ups and drops on the interchange tracks, even though they are in the MA&N yard at the time (although the interchange tracks may technically be CSX's anyhow).  When MA&N is working those tracks, they're on their own channel.

MA&N has trackage rights Utica to Rome, and goes to the CSX road channel when on CSX.  Once clear of CSX, they're back on their own channel.

Another case of "it depends."

When I first got into this hobby, I programmed all the NS channels into my radio. It got annoying as the police channels were always squawking but I couldn't hear anything (too far away). I may put the Reading yard in just to see what I hear.

Field radios have access to the full spectrum of FRA authorized radio channels. Radios on locomotives get used all across all the railroads in the country and need to be able to conduct business on the proper channels that are in effect on the particular carrier and location where they are at any moment in time.

Fixed location radios have their access limited to the channels that are appropriate to the specific location.  If there is a Yardmaster with a radio, the channels available to him will most likely be limited to the Road Channel on the subdivision and the Yard Channel assigned to his yard.  He will not have access to the Dispatcher's Channel nor will he have access to the MofW Channel.

The Train Dispatcher will have access to the Road Channel for the subdivisions he operates (normally, those subdivisions will all have the same road channel).  The Dispatcher will also have access to the Dispatcher's channel - he doesn't have access to the Yard Channel(s) or MofW Channel.  Dispatcher frequently have trouble making contact with trains that are in Yard Limits as they may be monitoring the Yard Channel.  When necessary, they may call the Yardmaster to have him contact the crew so they can converse with the Dispatcher.

Everybody on a segment of railroad will have access to the Road Channel for that segment of the road.  When it is necessary employees of to contact each other, the initial contact is initiated over the Road Channel, if the conversation will be about 'involved' issues or Mandatory Directives the parties will take their conversation one of the 'special' channels - Dispatcher, Yard or MofW.  The Road Channel is a party line for all employees, the 'special' channels are semi-private conversation spaces.

Needless to say, different railroads occupying the same geographical area will each have their own series of radio channels so that each railroad can conduct its business without getting trampled by the other railroads.

In the Baltimore area you have CSX, NS, Amtrak, the Canton RR, and Tradepoint Rail all operate on the airwaves with their radios.

Radios on locomotives get used all across all the railroads in the country and need to be able to conduct business on the proper channels that are in effect on the particular carrier and location where they are at any moment in time.

Especially on short lines, the radios may have specific, commonly used channels programmed into the radio.  So you may hear "go to channel 2" versus the actual AAR channel.  

We have five "channels" we regularly use - two of our own for road and yard, one that keys our repeater, one for the shortline we run on, and one for their repeater.  They also have another channel available - we rarely use it, and few of our radios have it programmed.

Many is the time, when listening to CSX, that I"ve heard the DS say "go over to 49" (or whatever the DS channel is), referring to AAR channel 49.  

Hand-held (portable) radios generally are programmed for the required local frequencies.  They aren't as likely to roam the system as the locomotives.

I've heard it suggested that railfans who travel a lot program all of the AAR frequencies into their scanner.  There are now almost 200 AAR frequencies since narrowbanding occurred.

When I was a DS, we had access to a couple yard channels.  We didn't usually monitor them, but crews could tone on them, and we could talk to them.

That sucks.  Sometimes I'd get bored in the afternoon when there was a lull, and listen in to the one yard channel when I knew their daily turn was building.  It almost always needed the signal and permission to reverse to make their doubles.  So I'd listen in and when I heard the engineer tell his conductor he would have to call the DS (me) for the signal - poof! It would pop up without him needing to play the song of my people.  Always caught them a little off guard.

A penalty brake application also occurs when the alerter/RSC finishes counting down without being reset.  It can also occur when any of the systems mentioned malfunctions, which is probably more common than actual unsafe events. 

As for getting in trouble, your mileage will vary from railroad to railroad depending on how the locomotives and monitoring systems are set up, and on the individual manager who receives the message.  CN's does not generate automatic tattling messages below 10 mph.

Alerter, cab signal drop not acknowledged, PTC/LSL enforcement if it doesnt think you are slowing down enough (PTC can do an emergency application if it really freaks out), brake fault, probably some other things too.

Shortline railroads used to have a limit of 400 miles in length.  Regional railroads are anything that isn't a Class I railroad (not many of those left any more!) but are too big to be a shortline.  The Wheeling & Lake Erie, Montana Rail Link, and Rapid City, Pierre & Eastern would be good examples of regional lines.

That is usually the case, though shortlines/ regionals do occasionally buy new locomotives:

At well over a million a pop for new locos, and $100K for used (obviously generalities, but for now...), most short lines don't have the cash for a new loco, unless they've got some business that's going to generate sufficient income to pay for it.

Oftimes that's what you'll see happen on a regional - they get a new customer who justifies the expense, so they go for new.
