• It only protects speeds of 40, 60, 80, 130 and 140 km/h. So when there is a local speedlimit of 100 km/h, the system will still allow 130 km/h.
• When a change in the speed limit is detected, next to a visual signal to the driver indicating the speed limit, it will sound a single "ting!" sound.
• When the train exceeds the speed limit, a continues bell sounds ("trrrrrrrrrring"), until the driver breaks.
• When a slower speed limit is in effect, and the train is breaking, the system will give three bells when the train has come below the speed limit ("Tring Tring Tring"; sounds like an old-fashioned telephone), indicating to the driver he doesn't have to break further.
• If the driver does not react to the overspeed-sound, the system will apply the emergency breaks, until the train is at a full stand-still. The driver can not overrule this until the train has stopped.
• And there is also the deadman-switch; the driver has to release it and press it again (usually, it's a foot pedal) every 30 seconds while driving. If he doesn't, a buzzer will sound. If the doesn't react within a few seconds, it will trigger another emergency breaking.

The RET just calls it ATB, as they find it easier (Automatische Trein Beïnvloeding). Yes, it functions similar to the ATB-EG system (EG stands for "Eerste Generatie" - first generation)the railways use, trough track signals, but there are differences;

There is also "ATB vv" (in fact "ATB-EG vv". the "vv" stands for "verbeterde versie" - improved version). This consists of three transmitters next to the track in front of important signals. When the signal is at danger, the system will set a breaking curve (just like in the RET ATB system), which the train driver must stay ahead of (exceeding the limit... another emergency break). This curve will force the train to stop in front of the signal, until it clears. This is to solve the issue that the standard system won't protect speeds below 40 km/h.

In the simulator, these sounds are missing....(as it is just a modified RET ATB system ). But the correct speed limits, according to ATB-EG, are enforced.

(So you will be able to use the train in Rijndam 1985 on Rijndam Noorderpoort - Noordvliet - Rijnwoude - Panbos, but it's better to avoid Rijndam Noorderpoort - Rijndam Airport)
