ATB - AutomatischeTreinBeïnvloeding - 1• Current Dutch signalling system gives allowed speed at acertain location• Until introduction of ATB: no protection of obeying thisspeed limit by the driver• Several (severe) incidents occured. Harmelen incident(1962, 92 casualties)) speed up the already ongoingdevelopment and introduction• Currently, all main line’s in the Netherlands are coveredwith ATB.11 june 2011 ATBe in steam locomotive’s

ATB - AutomatischeTreinBeïnvloeding - 3• ATB compares allowed speed and actual speed• ATB warns as soon as actual speed exceeds allowed speed• ATB guards reaction by driver• ATB initiates emergency brake when driver fails to react• Implemented in two versions:a. ATB EG: via track current, static speed profileb. ATB NG: via balise, brake curve11 june 2011 ATBe in steam locomotive’s

ATB-VvSpeed• No guarding below 40 km/u• Several incidents passing a Red signal• Introduction ATB Vv• Introducing brake curve for a set of signals with aspect Red• Beacons indicating ‘stop’ or ‘no stop’ at fixed position infront of signal and optionally a release loop.Distance11 june 2011 ATBe in steam locomotive’s

Towards ATB eenvoudig:ATBe• After introduction of ATB, some classes of rolling stock werenot equiped (maintenance stock and historic collections)• Development of “low cost” FPGA/DSP-based hardware andappropriate software• Simplification of a ‘standard’ ATB system (i.e. mainly: nocab display) lower safety level lower system cost• Introduction of 2-stage intervention:a. siren (oportunity for driver to initiate brake to standstill)b. in case of no or insufficient reaction: emergency brake(opening brake pipe)11 june 2011 ATBe in steam locomotive’s
