Crusher:
I used to work on the DM&E, your plant is probably on what once was my territory. In those days, your problem could have been resolved by a call to my office in Pierre. I would have come out and investigated the problem, and would have tried to get everyone co-operating again.
Apparently, the DM&E management saw no value in this kind of service, so pulled its field managers. If the small railroad didn't care, I see no reason why CP Rail would.
My comments and previous advice to you still stands.
COEN77,
All US railroads are required now to use the system you described. An important point is that the request to go between cars has to be acknowledged by the engineer before being acted upon. The precise steps the engineer must take vary between railroads, but have to be part of the Operating Rules and be approved by the FRA.
Some railroads call this "Three Step"; "Red Zone"; "Set and Centered"; but it all means the same thing. Not all railroads require an application of train air each time, but in any case it must be applied if needed to keep cars from moving (for instance, if the train is stopped and held by the independent brake on an ascending grade, the slack is going to all run out. The rule also forbids anyone from entering the danger zone until movement of the cars has stopped. You can't jump right in there as soon as your request is answered by the engineer).
I heard of one railroad that went so far as to require the engineer, in addition, to move the isolation switch to "Isolate" each time. That, to me, sounds like extreme overkill, but that's the way it is. Maybe he should have to pull out the reverser lever too, and put it in his pocket!
If the three tracks you work on are all owned by the same shipper, the Blue Flag Rule should be uniformly applied between them.
This is just common sense to avoid confusing the train crew. Lots of times train crews may be sent out on runs they do not normally make, and have to learn the customers as they are serving them. It really isn't supposed to work this way, but believe me, it does.
I've never seen Blue Flag protection used by an industry that used another color besides a blue flag or light. Although on private track it legally could be, it would really be a dumb idea.
On the railroads' own track, the Blue Flag is only supposed to be used on locomotive servicing or repair tracks; or car repair tracks. These are supposed to be designated in the Employees' Timetable. A platform track in a passenger station might be designated a Blue Flag track if passenger trains are inspected or serviced by Mechanical Department people during a station stop. On railroads' track, the Blue Flagged track has to be protected by switches and derails that are locked with special Blue Flag locks with keys that are issued only to the Mechanical Department. The idea is to make it nearly impossible for any train or engine to enter the track where the work is being performed. In addition to the track being flagged (in both directions if it is not a stub track) a locomotive under Blue Flag Protection will have a Blue Flag (usually actually a blue metal sign) attached to it. It will also have a Blue Flag draped over the control console as a not-so-subtle reminder.
Blue Flags are not normally carried on locomotives while in service, although I don't think it is a violation to have one on the locomotive while in service, as long as it isn't being displayed. They cannot be applied by the train crew, so there really isn't any reason to carry one.
