I have never ever seen that happen where MOW equipment or welders would make a signal light up and flip on and off must be the signals are wired diffrentley in the West compared to the Northeast?
Even with a malfunction, I would have thought two things would happen: #1 the signal should latch, not flap, and #2 latch to a failsafe state, in this case red. Unless this line is still using pure relay logic, and not modern CPU/software based systems.
Nah there is mainetenance going on. Assuming the signal is approach lit, it could be a high rail truck activating the circuit intermittently, or somebody working on a rail, or whatever. The signal is at 210, and one of the MOW people said he was at 212.
Alot of signals are designed to show the approach aspect when changing from clear to stop so that explains the amber.
Out east I see this happen sometimes in rain, when the water shorts a block.
@Eng8492 There were quite a few welds being shot within the 212 vacinity that day IIRC. And yes, approach lit. And this was in early 2009 no less; these signals along the ex-WP here have since been ripped down and replaced with newer tri-lights, last December. This signal at 210 was always interesting, I thought. It was the only Safetran, as far as I know, anywhere along this route. The majority were all old WP target signals until they were ALL replaced. New ones are approach lit as fuck..sucks
I see what you mean malfunctioning. They've got the colors backwards with red on bottom and green on top. Anyone knows that red should be top priority like it is on about several million traffic lights. It doesn't matter wherther you see the green or not, the MOST important signal is STOP!!!!! So why would the railroad relegate red to bottom position?....just to be different? Not very safe. Surpised the DOT signs off on that.
@JetMechMA The malfunction is the indications lighting up continuously at random and dropping, flashing, etc. All Safetran tri-light signals in the US that I know of are configured with red and green opposite that of what you would find on a standard traffic light because of snow. If snow should build up on the top of the signal, red would be the most important indication to identify. Anything else would otherwise be noted as a "clear" or other proceed indication.
I've seen sometihng close to this before, on the EJ&E in Warrenville, the intermediate kept switching from red to green, made a UP coal stop for 20 minutes.
onetime in cahokia Ill on the signals at where the S P and Unoin Pacific comes together the signal was yellow for approach as the train passed by it went from yellow to green and then red and went off for about 5 min i was like ahhhh no that is not suppose to happen
@robertgift A Controlled Point signal certainly can be changed remotely (or locally from the vital circuit interface cards), so it's possible that this is what we're seeing here (though it could be a failure of the ElectroCode or whatever other communications protocol they're using). As for the hi-rail vehicle--generallly speaking, a normal (and correct) hi-rail installation on a vehicle will result in the wheels being electrically insulated, so shunting should NOT occur.

Wow, that's a new one to me. Can't say I've ever seen a signal do quite a light show as that!

Perhaps the Pettibone was not shunting properly. That could cause the signal to bob.

This is nothing, that has happen ti me. They test the signal from where ever they control them.

Testing or working on the signal system?
Does that equipment at the end shunt the track?
Or are the wheels electrically insulated?

Great shot, that is kind of odd how it did that. The railway crossings at my house are crazy. I will be posting avideo of them acting really strange.
