Speed limit überwachung

[LCYCowboy]

Hi People,

If I am driving a train with PZB U (untere) at 80km/h and I pass a speed limit warning of 70km/h which you need to acknowledge with the Wachsam Taste this then puts the train into 1000Hz monitoring.

Does this mean that I have to slow all the way down to 55kmh (to prevent a Zwangsbremsung) and wait for it to clear before accelerating up to 70km/h again?

Absolutely loving this sim (after many thousands spent on Dovetail games, and still getting rubbish).

Exactly.

Fortunately 70 km/h is rather rare in German signalling. You often find 60 und 80 km/h. So when 60 is shown, you have to drive 50 km/h (you shall always be 5 km/h below the PZB limit) and when 80 is shown you can avoid the PZB by passing the distant signal with less than 95 km/h.

Thank you for the answers.

It all makes sense (although I didn't know about the 95 km/h at the Vorsignal.

Hi Cowboy,

the 95 at the distant signal occur through the following process:

To avoid costly slowing down and afterwards accelarating heavy freight trains at point, where PZB is securing an announcement of a speed restriction to v (70 km/h < v =< 90 km/h; for v > 90 PZB is not installed at the announcement), DB used a "speed control section", consisting of three PZB-track-magnets. Any train passing that poin faster than a certrain speed (for v = 80 it's 95) will receive a 1,000 Hz influence, trains slower will not. Driving in awareness of energy saving (and with good track-knowledge) will use this to avoid waste of energy.

Thanks for all the replies.

One more question about speed limits. I often drive trains into Westerland (Sylt), and near the end as you approach Westerland the speed drops to 50 km/h and then 30 km/h.

I always seem to get a zwangsbremsung just before the 30 km/h limit. I can't work out why. The way I can avoid it is by slowing down to 30 km/h really early. I have been looking out for magnets on the track which could be causing the issue, but can't figure it out.

Thanks again for all the help.

Neil.

ps. I have started another thread about Zs 1 signals.
