As passenger safety and operational efficiency in the rail industry are increasingly being emphasized, it is becoming necessary to install an effective video surveillance system that covers more than just the interior of a train, but the exterior as well. Cameras deployed on the train exterior can assist train operators to ensure that doorways are clear, which is particularly important as this is the most likely place for accidents to occur. In addition, cameras deployed on the exterior of trains allow safety checks to be performed remotely, which helps operators move closer to deploying automated trains.
The pantograph malfunctioning is a critical issue that needs to be considered as it often results in long delays and huge financial losses. Without cameras on the exterior of the train, it is difficult to determine whether the pantograph malfunctioned during normal operations, or the fault was due to external factors. When there is clear footage, it is easy for train operators to determine when and why the pantograph malfunctioned.
Within the rail surveillance industry, a new trend is currently gathering momentum. Due to frequent requests from train operators, coupled with significant advances in technology, a desire to install surveillance cameras on the exterior of trains is becoming prevalent throughout the rail industry. However, before these desires are realized, significant technical challenges have to be overcome. This white paper examines these challenges and introduces new technologies that are currently being utilized in order to make camera installation on the exterior of trains not only possible, but also beneficial and profitable to train builders and operators.
