Hi everyone, I dont Know if this is the rite area to post it in but it seemed rite to me.
Have any of you seen a Safetran Signal look like this?
If So can you tell me what it means?
Scott (amtrakey)
I think thats a safetran, and I think it means medium approach, which usally means they have reduced speed to some degree for going over switches or something like that. Ill half to pull out my CSX signal manual (some engineer gave it to me one day) but first, is that taken at St. Denis Marc Station just outside of baltimore MD?

...generally...
....anything with a green light, is a Proceed Signal.
Depending upon whether you have it on a mainline or siding, it could mean the wrong signal is applied.
The Safetran signals we have apply to Left Diverging, Right Diverging, or Interlocking signals.
Often, a change in signals on the main will result in a Clear Signal, but comming off a siding or second main may have a yellow aspect added(approach diverging, clear or at approach speed, about 30mph).
If the signals added are correct, you are warned of approach speed prepared to stop at the next signal...you may proceed at track speed, but must obey the next signal aspect.
It is not a "Clear" signal, but is a "Proceed" signal aspect.
No green or clear, means approach, at slow speed(15mph)...the next signal may change as you approach prepared to stop at signal...or proceed.
If the next "block" is unoccupied, your signals may be wrongly applied. They will not function correctly.

Torpedo423: Yes that is outside of the marc station at St. denis, i used my phone to take the pic.
Backyard: I really dont know what it means but i think they were not functioning rite cuz not even the train was through the signal that rang up and showed there for at least 2mins.
But i always thought safetran signals only lite up in a row like,
Orange
Green
Red
or
Red
Orange
Green

The reason it may have come up after the train passed might be cause of the switches there, if they aligned it from 2 to 1 and 1 didn't have anything in that block it might have shown clear or what ever it's displaying there.
I thought the same about the signals, but now that I realized that the ones at St. Denis are Safetrans, I am corrected.
red = STOP
yellow = APPROACH
flashing yellow = ADVANCE APPROACH
green = PROCEED
blinking red = RESTRICTING
You read the signal from top to bottom.
So if it reads:
RED
YELLOW
RED
This means: Diverging Advance Diverging.
So you'll go off the main track, onto a siding where you must be prepared to stop at a red before going onto the next diverging route where there will be another control point.

what's a normal map?
mmm i dunno Evan, i have had to read your post a few times and im confused by it.
the 1st (top) head represents your normal aspects, as if the signal had no other heads, the 2nd (middle) one represents medium aspects, and the 3rd (lower) one represents slow aspects.
the way ive learned things is that if any head is not red then the other red lights dont mean anything at all. (the "if they are red then they aint read at all" rule of thumb). so id say the red, yellow, red would simply be a medium approach or diverging approach. medium or diverging speed because its the 2nd head, and approach because its yellow.
as for the first image the bottom green typically means SLOW CLEAR, so combine that with the top yellow and its an approach slow indication. it means just the same as a single yellow, except it tells you to approach the next red signal at slow speed.

I'm going by the Union Pacific signal system. It might (and probably is) different on other parts of the United States. Union Pacific gave my school their training program for learning signal aspects and indications so I'm reading straight from the source. But like I said, signal A&I's on the east coast probably vary in several ways compared to signals on the UP system.
Some signals have multiple aspects they can give, depending on the signal setup and the number of tracks the signal is controlling. The picture's signal controls three tracks on that block, you would read the aspect from top to bottom depending on what track you're on. Reading the signal from left to right, (just like a book), the MARC 7749 is being governed by the middle signal. I can't tell what the indication is based off of the angle of the picture, but it is kind of amazing to see how many various signal systems there are across the United States and up into Canada.

in some small ways there might be some differences, but its generally the same across the US. there are routing indications and speed indications, but most of the time you will see they show the the exact same thing for each circumstance.
how so? you read the signal that gives the aspects for the track that your train is on, not any of the others, they dont pertain to you. when you are in a train driving, you dont know how many tracks a signal is controlling- nor does it matter, its just up to you to follow what that signal says that is governing your train.
MARC 7749 isnt governed by any of those signals as it is coming toward the camera... the signal aspect that it is following is back in the background near that other bridge and facing the opposite direction from the image point of view.
Yea the aspects & indications will remain the same, I've seen a few funky looking signal setups that's all.
What do you mean how so? If you're on a track that is governed by a signal, you follow to what aspect that signal is giving that is on your track.. I guess if system special instructions told you otherwise you would abide by the rules given per SSI.
Meh I couldn't tell what the direction of movement was.

because you said:
you would read them the same no matter what track you are on, for that particular track. you dont ever read them any other way. maybe its not what you meant i dunno. in the end, the signal reading in question was an approach slow, just like i outlined in my other post. it means the next signal is red, approach it at slow speed through the turnout. it would mean this on UP as well.
Sorry mis-communication on my part.
