HI everyone I got a question about some signals that. I go past everyday these signals are on the CP/Amtrak line between downtown milwaukee and the southside. When i go past them they are always red or yellow or even flashing yellow. But it seems like they never go green or if they do I don’t see it can someone explain this to me. Also on the same set of tracks I get a pretty good view of the tracks from where. I work and lately they have been doing alot of track work and most trains have been using only one track or the other even the amtrak hiawatha trains but also on days when the. Trains are using only one track if a train has to stop like frieght train which seem to be stopping alot right by where. I work how do trains leaving the city to go south how do they avoid hitting one another. Along this length of track there are no switchs to move trains to another track to avoid a big boom.
railfan 619 which bridge are you refering to, the Menomonee River bridge just south of the depot, or the Kinnickinnic River Bridge (KK Bridge)? In either case there are signals governing movements in both directions on either track. There is a double crossover just south of the Menomonee drawbridge. If you are refering to the KK Bridge then the next crossover south of there is at Lake about 6.5 miles south of the KK Bridge. The Dispatcher in Minneapolis will only allow trains to move in one direction at a time over the temporarily single track line.
No the signals I’m talkin about are between holt/morgan ave and the cematary on milwaukee’s southside there are two signals one on each side of the tracks one is always red or yellow and the other signal is always flashing yellow but they never are green.
Have you ever seen them with a train coming up to them?
Yea I see trains go up to these signals everyday. And they go right though them most likey with permission from the dispatcher.
Hi, I am not an expert but if these signals have a number board mounted under them, then they are permissive block signals. Permissive block signals allow a train to approach and proceed at a reduced speed, prepared to stop at the next signal that may be more restrictive. An absolute block signal will not have a number board mounted on it, and if it is red, it means stop and stay until cleared (green). These are probably permissive signals that you are seeing.
