Short train = no FRED?
Posted by MP57313 on Monday, March 28, 2005 9:02 PM
This afternoon a local on the BNSF Harbor Sub (Lawndale, CA) had the standard 3 engines...with only one tank car; there are often 10-20 or more. No FRED or red flag on the tankcar...wouldn't think you'd need one. But is there a minimum train length where a FRED makes sense or is required per regs?

On a yard to yard movement, under two miles in daylight, outside of CTC, no rear marker is required.
And, any movement that is withinn yard limits requires no marker.
Yard limits are not necessarily confined to a yard proper, they can extend for miles....
Train length makes no exception...

From the GCOR, General Code of Operating Rules

5.10 Markers
A marker of the prescribed type must be displayed on the trailing end of the rear car to indicate the rear of the train.

5.10.1 Highly Visible Markers
Display a highly visible marker at the rear of every train as follows:

From 1 hour before sunset to 1 hour after sunrise.
When weather conditions restrict visibility to less than 1/2 mile.

A marker equipped with a functioning photo-electric cell will automatically illuminate at the appropriate time.
When an engine is operating without cars or is at the rear of the train, the trailing headlight illuminated on dim may be used as a marker. Inspection of Marker

When a highly visible marker is required, a qualified employee must inspect it at the initial terminal and at each crew change point. To determine if the marker is functioning properly, the employee will inspect it by observation or by telemetry display in the cab of the engine. The engineer must be informed of the results of the inspection.


5.10.2 Alternative Markers
Display a reflector, red flag, or light fixture at the rear of the train as the marker when any of the following conditions exists:

A highly visible marker is not required.
A defective car must be placed at the rear for movement to a repair point.
The rear portion of the train is disabled and cannot be moved, and a highly visible marker cannot be displayed on the rear of the portion to be moved.
or
The highly visible marker becomes inoperative enroute. If this occurs, notify the train dispatcher and move the train to the next forward location where the highly visible marker can be repaired or replaced.

I don't know if it's covered in the rules of thr road, I've noticed no FRED's on locals. If you're somewhat aware of the UP coastline, they have a switcher (local) that switches the mainline between Burbank Junction out towards Oxnards. They may divide it up between two locals. I haven't seen FRED's on this kind of operation.

Several times i have seen Coal trains with a operating FRED on the rear facing DPU engine, even tho the unit's headlite is on dim, as required. These were BNSF coal trains north of Denver, running both ways. Possibly a malfunction in the Guages in the rear unit???

Well, I could say something about the point and a comb over, but I will keep my tongue civil and just say - the ones that I have seen, were flashing. Seemed a little redundant to me, but hey, I just watch.

How soon they forget.....BN had a penchant for running trains into each other on "dead-end" branches, including some classic rear enders...The Golden Sub. incident was classic...look it up.

And,
One of the function of the rear end device is the ability to put the train in emergency braking via the radio signal, so, even if the rear unit fails to respond to the lead, the engineer always has the option to big hole it with the fred...

Last, the flashing light is much more noticable that the locomotive head light on dim.
At night, you see the fred from a long way off, but the dim headlights often get lost in the background lights...

a FRED was what the first generation of devices was...all they where was a flashing rear end device..the second generation just had 1 way communications...the 3rd generation have 2 way commincation capibiltys... they send a signal to the lead (or any locomotive that has the proper ID code dialed into the HTD)... that shows the rear brake pipe air pressher...if the marker light is on or off..and if the rear end is moving... they are also able to recive a signal for the HTD to put the train in emergancy from the EOT...

First, the politically correct name used in GCOR and Class 1 operating rules is "EOT" (End-ofTrain device) as "FRED" is potentially discriminatory.... don't you love the world of political correctness?

Sceond, according to US federal law, CFR Title 49 Section 232, all trains operating outside yard limits must have an accurate air gauge on the rear end of the train. While this does not necessarily require an EOT unit as such, it is certainly the most convenient option. If there was no EOT device, then most likely there was also some air gauge mounted on the back that may not have been noticeable to a casual observer. The only exception where rear-end air gauges are not required are on "landlocked" railroads (that have no interchanges with the national rail network in some form), moves within yard limits or light engine moves (no freight or passenger cars or cabooses). In the old days, the caboose fulfilled this purpose as it has an air gauge inside of the caboose for the rear-end crew to monitor.

Most EOT devices in use today are 2 way EOT devices, which are EOT's that transmit air line pressure information to the locomotive and also, in the event of an emergency brake application, can vent the train line air pressure from the rear end of the train.

You don't need an acurate air gauge to operate outside of yard limits. The only times you need the air gauge is to perform Air Brake tests.
The regs do require that one way and two way EOTs to be equipped with an air gauge.
With the exception of certain trains, the regs require trains to be equipped to initiate an emergency application from the rear end. Can be a EOT, DPU or a manned caboose in radio contact with the head end. If the capability is lost, trains outside of heavy grade areas can continue to operate not exceeding 30mph until the capability is restored.
One of the exempt type trains are local trains with less than 4000 trailing tons and operating over one crew district outside of heavy grade areas.
Most time our way freights operate on the main line with only a red flag on the rear coupler. The conductor has a hand-held air gauge to perform the air brake tests when needed.

CSX enginner, I am not sure if this is a question or what... I believe that is what I said, except you rephrased it incorrectly. Only 2-way EOT devices can do this. Therefore, not all EOT devices have this capability.

Jeff,

I am afraid that you are mistaken in regard to the need of an air guage. Federal law requires that ALL trains operating outside of yard limits must have an accurate air gauge WITHOUT EXCEPTION. I have confirmed this with an FRA field inspector. Any train operating without one is in direct violation of federal statute.

However, it is true that on certain types of trains on which you do not need 2-way EOT capabilities, you could get away with not having an air gauge connected on the rear of the train at all times, so long as long as the conductor has one somewhere on board that he can use when needed. In these cases, federal law still requires that a "highly-visible marker" be used on the end of trains from 1 hour before sunset to 1 hour after sunset.

The only exceptions to the air gauge and visible marker requirements are rail lines that are exempt from most or all FRA regulation, such as tourist only railroads or "landlocked" railroads.

You better go back and read 49 CFR 232 subpart E again, paying attention this time. (Since you appear to have castigated a couple of other posters for having either missed or mis-stated small details, it seems in the spirit of fairness to bring this up.)

The presence of an "accurate air gauge" on the rear of the train is NOT a necessity (although an air-pressure sensor with +/- 3psi accuracy and -1psi differential IS)... see 232.403 (4). You might claim that "a means of visually displaying the rear unit’s brake pipe pressure measurement" is what you meant by "air gauge" -- but one then would have to wonder why 232.403(4) specifically uses the words "air gauge" and then ADDS a separate, additional functional-device description...

On the other hand, I can find no indication whatsoever in subpart E that an EOT is "not necessarily required" as you claim. What is not necessarily required (under the circumstances delineated in 232.407) is the use of a *2-way* EOT. A radio-telemetric EOT (as defined specifically in 232.5) is mandatory for all operations "operating on track which is part of the general railroad system of transportation." See 232.3 -- if you don't need an EOT, you're not bound by the air-gauge requirements either, as it's the whole of part 232 that would be excepted. In fact, subpart E in its totality will continue to apply in at least some cases where other parts of 232 would not apply.

You might also mention that all new EOT devices, by law, have to be 2-way (or better), and this goes as far back as 1998. Again, you might note that while earlier 2-way devices are grandfathered into 232-405, the rulemaking is perhaps pointedly silent on the subject of older 1-way devices.


Finally, everyone might note that the FRA says nothing about markers, flashing or otherwise, colored or not, as part of the EOT device with respect to brakes. That's -- I think rightly -- an operating-rules issue. (As is the definition of a "train" as opposed to a yard move, etc., I think) From an engineering standpoint, it makes reasonable sense to incorporate a 'highly visible' function into an EOT that already requires sensors, a radio, and a relatively long-life battery. But just because you don't see a blinking light or whatever is no indication that a 'legal' EOT or equivalent (e.g. functionality built into a trailing DPU locomotive) is not present and active...

I'd love to be corrected if I'm not interpreting the present rulemaking correctly (note that the 2003 Title 49 CFR 232 reflects a number of changes in these regards from the 1998 version).

This was originally a double post. Not intended as such. I think I'm figuring out how this happens -- if I have multiple windows open in IE 5.5, and quickly jump back to the main page on the forum, I sometimes observe the 'flood control' message -- indicating that the software thinks I'm trying to post something again within 90 seconds.

I'm not sure exactly what's firing this behavior, and I'd be interested to see someone trace or debug the sequence of events at the server to see whether the problem is there. I don't think it's a bug in my client (Microshaft though it be!) but there may be configuration details that are contributing to the problem.

Apologies for the duplicated post. It's gone now.

no..you said that an EOT can vent the air when an emgerancy application is made....i said that the EOT can infact make its own emergancy applicaition.... the way you worded it... you make it sound like that if the engineer dumps the train with the auto brake from the head end.. the EOT will vent air as well as the brake valve... im just stateing that the EOT itself can make its own emergancy application....by flipping a switch on the head end..... and yes...your correct that it only can be done if it has 2 way capabilitys...and only if the 2 way abilitys are armed....

Not to get to legalistic here but i really do not see any other interpreation of "a means of visually displaying the rear unit’s brake pipe pressure measurement" besides that of an accurate air gauge (which in the context I was using also includes, but is not limited too, all EOT devices). If you know of any other instrument fitting that criteria, I would be more than welcome to learn what that might be.

Yes it is true that all new EOT devices must have 2-way capability, although existing 1-way EOT's are permissible under certain circumstances. I expect that eventually 2-way EOT devices will be the only devices permissible.

Why are all trains required to have EOT's? Have you never seen a caboose operating on a train before? As indicated in Subpart E of 232 .... for those of us that were reading it with our eyes open anyway.... there is no statement indicating that 1-way EOT's ARE required in any circumstance, only designating the performcance and design standards for these devices. The only devices that are required are 2-way EOT's with the exceptions provided in that subpart, which include, among other things, staffed cabooses. I see no statement indicating that if a two-way EOT is not used (when it is not required) that a 1-way EOT is required. It makes no sense why, if you are not required to use a 2-way EOT, that you would use a 1-way EOT when you have a staffed caboose on your train. The most important thing, which is what I was originally trying to point out to the original posters, is that common-carrier railroad lines cannot get away with having no air gauge capabilities of some sort because that would be a Part 232 air brake testing violation.

drfizzix....
i think your little confussed..... the only times you need to have an air reading on the rear of the train is in grade territory (designated in the timetable special instructions) and have to have 2 way capibiltes.....and in dark territory so you know your train is still intact if you stop...unless thier is someone that can verify that last car number.... a defect detector that shows the same axel count as a preiouse defect detector...... (the same thing apllies even if you have 2 way telemitry and you loss communications)...
also...the air gage is needed for a brake test... if your on a local with 2 cars...and its daylight...as long as a test was done with a gage or the cars where pretested with an airslip....a red flag is all that is needed..unless your in territory that says you have to have an EOT...
