Extended Signals Speed Control

[boleyd]

Signals that extend their speed limits to the next signal are a real pain.
The only way to mitigate this ridiculous situation is to install another signal in front of the speed control signal to shorten the "controlled area. This is the "dummy" signal. Place it some feet in front of the limiting signal and the fool stops its extended control there.

Is there an identifying characteristic to separate extended-signals from more benign signals?

Is there a common process to eliminate this procedure other than tagging all the offenders with dummy signals?

Is this extended speed zone a common practice on railroads in the USA? How is it implemented on railroads? That is, how does the person operating the train know that they are in an extended zone?

What type of signals are you referring, North American types?

Yes, in the NorthEast of the USA. I think the "extenders" are mostly "06".

Unless you're using 06's for junction control, use only 05's/04's, the intended use for the 06/08 is to control speed of trains speed through junctions and interlockings, crossings. So, unless you are using 06/08's for junction control or interlocking purposes, stick with 05/06's, along the route.
