PTC is forcing some new excitement in the world of signal communications.
Rather than point-to-point radio, railroads are experimenting and some are implementing a specialized version of the GSM mobile phone system just for railroads called GSM-R. A system also being put in place are VSAT satellite terminals but the rain fade problem with satellite signals makes me doubt their viability.
blue streak 1 BaltACD: Signal trouble was vandalism to the signal equipment at Carroll's control point in Baltimore. 4 Camden line trains did not operate on time - 1 was 14 minutes late and the other 3 were less than 5 minutes late. BaltACD: Thanks now another today THUR. Brunswick Line train 874 (5:25 am Martinsburg departure) is approaching Brunswick station 10-12 minutes late due to signal problems west of the station.

While MARC may have reported it to their audience as signal trouble - P874 was Efficiency Tested between Martinsburg & Brunswick. When E-Testing is done, both CSX & MARC officials take part in the testing. The same thing occurs with VRE when they are E-Tested.
Never too old to have a happy childhood!

blue streak 1 Another signal delay on the Camden line this morning. All Camden trains are expected to operate 12-15 minutes late due to a signal problems north of St. Denis station. Updates will follow as information is made available.

blue streak 1 As I posted earlier the track geometry and rail integrity tests eastbound track found a lot of rail problems. CSX has posted speed limits on different sections of that track until they are all repaired. Delays to MARC usually 10 - 15 minutes with occasional 30 minute delays.

CSX is now replacing much of the eastbound track on the Brunswick line.
n012944 Short of a bunch of broken rails, one thing should really have nothing to do with the other. Has anyone said what these signal problems are? Are they really an issue with the signal system, of is it something like grade crossings malfunctioning, and the delays from slowing down and or flagging crossings are being reported as signal delays. If that is not the case, the only other thing I can think of to cause this many delays would be if this is code line territory. Code line breaks quite often during bad weather, and the meth heads love to steal it and sell it for scrap.

Cannot answer the code line question. Anyone know. As I posted earlier the track geometry and rail integrity tests eastbound track found a lot of rail problems.

It must be nice. Much of the old C&O on the west side is still old codeline. The ex PM lines across Michigan are really bad, although CSX has been slowly changing it out to radio code.
An "expensive model collector"
Code Lines in today's (at least CSX) is somewhat of a misnomer. Most control points have become radio controlled in the field, however, to effect this radio control from the CADS computer in Jacksonville the commands are sent via commercial telephone lines to various radio control 'hubs' that service one or more control points. Despite having decentralized the dispatching offices, CSX runs the CADS computer from a centralized location; each decentralized office also has computer hardware that can be used for back-up purposes in the event of a catastrophic failure in Jacksonville (in 23 years of my personal experience - there has only been 1 incident that caused CADS failure and that was a computer virus that crippled the CSX Main Frame computer and created communications issues that crashed the CADS system)
98% of the Code Failure that is seen is a failure of the commercial telephone circuit(s) that affect a particular radio node. It is difficult to infect Verizon, or the other telephone carriers with the railroads sense of urgency in getting the telephone problems diagnosed and corrected.
There are still wire thieves that disrupt operations at some sites, as even in radio code sites there may be need to run wire circuits from one end of a siding to the other; or other similar type situations.
n012944 blue streak 1: CSX had a track inspection vehice on the eastbound Brunswick line yesterday ( unknow if FRA or private ) and the number of slow orders placed is causing delays today of up to 30 minutes. Makes one wonder if maybe these track defects could have caused some of these intermitttent signal delays past few months ??

Bowie on the NEC is Amtrak maintained.
blue streak 1 TODAY MONDAY ANOTHER SIGNAL PROBLEM AT Bowie on CSX.
TODAY MONDAY ANOTHER SIGNAL PROBLEM AT Bowie on CSX.
CSX is currently experiencing issues with their signal system at AF. As a result, Train 330 is being delayed into Alexandria. The train is currently operating 26" behind schedule and should be on the move shortly.
CSSHEGEWISCH If my experiences with Metra are any indicator, "signal problems" or "signal failure" is often used as a catchall explanation for delays. A recent example: My morning ride on the Southwest Service was delayed a half hour on one day last week due to freight interference, probably due to a freight on the IHB at Chicago Ridge. A later canned on-board announcement stated that our train was about a half hour late due to signal problems.

Actually MARC is very careful to list actual cause. almost 75% of all delays are listed as due to freight train interferrence.
That being said a review from Feb 1 - Mar 9 haad over 15 signal problems mostly on Brunswick line but a few on Camden line.
Naturally we all assume that "signal failure" means that the signals do "fail safe." I hope my comments don't indicate otherwise, because I don't intend that in any way.
A few years ago - maybe 5 or 10 ? - there was a definite "false proceed" on CSX a little south of the AutoTrain terminal at Lorton. As I recall the situation, the very alert crew of a NB train on one track saw a green on an adjoining track for an apporoaching AutoTrain that was still behind them - and then saw and realized there was another train still within the block protected by that bogus green signal ! They radioed the AutoTrain to stop ASAP, and disaster was averted. Subsequent investigation and testing revealed defective insulation on the signal wires had failed prematurely, causing the "false proceed".
EDIT: Link to a thread here in 2008 about this incident:
http://cs.trains.com/TRCCS/forums/p/123445/1418324.aspx
So I wonder (speculate) if these numerous signal problems in the same geographic area are perhaps caused by the same or a related cause ?
There's an on-line compilation of these kinds of things someplace . . . [EDIT] see the "Ironwood" link in the thread that I referenced above, and this link for a more general compilation:

Now we hear that Amtrak had a failure south of CHI Union Station for 42 minutes that delayed METRA

efftenxrfe A CSX PR person ardently wants to quell the descriptive "signal failure." Signal failure, terrifyingly, means an erroneous permission to move when danger or catastrophe is beyond the signal. Any signal that slows, delays or stops some move 'cause of component malfunction, track circuit problem, protective device function screw-up, power failure, or burnt-out light bulb or...or....has not displayed a "false proceed" indication. It has succeeded in properly authorizing train movement.

I will give you that the RR definition of a signal failure has probably not occurred whereas a false green would be a signal failure. However CSX is having a major problem here for whatever reason as the signal systems fail safe very often. A check of the Cascades route - maybe 1 a month, Capitol corridor - 1 a month, Surfliners have seen none reported. The Worcester line that CSX has transferred to the MBTA (but CSX is still maintaining the last time I heard ) has also been experiencing a somewhat high # of signal problems
And another Thursday afteernoon:
Train 855 (5:15pm departure from Camden Yards) has been terminated at Savage due to freight train congestion and signal problems. Passengers will transfer to Train 857, which is currently approaching Dorsey
+ 1-----
Train 846 (4:13p dpt Union Station) is operating 25-30 mins late due signal problems near Greenbelt
So, is CSX ready for PTC? Or will PTC inadvertently make CSX better by replacing bad equipment they evidently refuse to maintain in a state of good repair?
and another failure wedensday afternoon on the Fredricksburg line :
