When traveling from Dresden via the Coswig branch, there is a GPA magnet that triggers at the wrong speed. The magnets are located close to where the Coswig branch starts (you can see the 1 Km track marker just before the GPA magnets in the picture below). The warning speed limit signal indicates a 120 Km/h speed limit (first pic below), but the GPA magnet will trigger under that speed (117 Km/h in my test) as you can see in the last picture. GPA stops the train at 117Km/h, when it should trigger if the train goes at 135Km/h or faster.
When entering Coswig the distant signal shows a green flashing light which warns you that the speed limit at the next main signal will be 100 km/h. The Lf7 showing "12" is only valid when the distant signal would show a constant green light. But since the signal speed is lower than the line speed, the PZB wiil enforce that signal speed of 100 km/h, therefore stopping you when you exceed it. I Hope you find this helpful
Yep, it is very helpful. Thanks! Guess getting used to the Hl signals is gonna be a bit more difficult than I thought.
