Driving aids
Memor-Crocodile
All signals on the main tracks in Belgium are equipped with the Memor-Crocodile system.
With this system, when a train passes a “double yellow” signal (meaning a light announcing that the next light will be red) the driver is informed by a warning light in the cabin. The driver must then press a button to confirm that he has seen the warning light. If this is not done, the train’s emergency braking is applied automatically.

TBL1
The TBL1 system (= Transmission Beacon Locomotive 1) is based on a trackside beacon which sends an electromagnetic signal to an aerial located underneath the locomotive.
With the TBL1 system, the driver must always confirm manually that he has received a warning that he has passed a double yellow signal (as for the Memor-Crocodile). But, in this case, if the driver confirms the warning, but, despite this, overruns the red signal, the train will be stopped automatically by emergency braking.

TBL 1+
The TBL1+ system (= Transmission Beacon Locomotive 1+) is based on a trackside beacon which sends an electromagnetic signal to an aerial located underneath the locomotive.
This system is similar to the TBL1 but has 2 major differences:
- An additional beacon is placed 300 m up the line from the signal in order to check that the train is approaching the red signal at a reduced speed (less than 40 km/h).
- The equipment used complies with the European ETCS system. Therefore, it is a long-term investment meaning that Infrabel will not have to adapt to European standards in the future, with simple changes to the system being enough.
By the end of 2012, TBL1+ will cover 87% of risks over the entire rail network.
