“…For this case, ETCS already includes the possibility to upgrade existing stationary signals with so-called Lineside Electronic Units (LEU) that grab the signalling information directly from the signal and then transmit them to the vehicle via balises mounted on the track. 5 This approach is for example used when ETCS is deployed in Level 1 configuration with Limited Supervision (LS) where ETCS components complement already existing signalling and interlocking systems. This type of deployment is furthermore the favoured realization for non-high-speed railway lines by Germany's main railway infrastructure operator DB Netz AG.…”

In recent years, a strong push towards driverless mobility solutions can be seen in many transportation sectors including railways. While the European Train Control System already specifies the necessary interfaces to open up the possibility of Automatic Train Operation (ATO) for mainline railway vehicles, required infrastructure-side upgrades of interlocking systems are time- and cost-intensive. Alternatively, a pure vehicle-side Automatic Train Operation solution can be conceptualized that relies on processing the same audio-visual input a human train driver would normally base his decisions on. This would require the vehicle-side detection of track-side railway signals to determine the vehicle’s movement authority and allowed maximum speed. Such a signal detection system could furthermore be employed as an Advanced Driver Assistance System (ADAS) or support autonomous shunting operations. To enable such a system, this paper presents GERALD, a novel dataset for a neural network based detection approach of railway signals. The dataset contains 5000 images from a wide variety of railway scenes as well as annotations for the most common types of German mainline railway signals. The material was gathered using publicly available cab-view recordings uploaded by railway enthusiasts on YouTube. Using a state of the art neural network architecture for evaluation, we notice promising detection accuracies despite GERALD being a comparably small dataset.
