“…In addition to the track circuit and axle counter, quite a few different types of train detection systems have also been developed and tested over the years, such as GPSbased systems (18)(19)(20)(21)(22)(23)(24), lidar sensors (25,26), radio frequency identification (RFID) tags (27)(28)(29)(30)(31), inertial navigation system (32)(33)(34), and others (35,36). However, most of these train detection systems have not been widely used because of reliability issues and safety concerns.…”

A train detection system is the basis of signaling and control in railway transportation, and there is a trend to apply multiple train detection systems simultaneously to improve reliability and safety. The ideal evaluation process for train detection systems should be able to determine their reliability and safety by considering the track layout, detection block, design and logic of the detection system, routing and frequency of trains, and train length (in relation to block length). Existing evaluation methods for train detection systems still require a few manual interactions and human judgment, which could be inefficient and subjective. Consequently, this research aims to develop a framework with automatic processes to generate all failure scenarios, calculate the probability of fail-safe conditions and wrong-side failures, and finally determine the reliability and safety index of the corresponding connection logic. Results of case studies demonstrate the applicability of the proposed framework to actual cases. The use of this framework can assist railways in identifying the appropriate design and logic of multiple train detection systems.

“…In literature, extensive research is performed in developing Wireless Sensor Network (WSN) inside [1] and outside [2], [3] train wagons [4], based on different communication protocols [5]. A typical WSN consists of several Sensor Nodes (SNs) spread across a train wagon and transfer their data to the Central Node (CN), some of these sensors have an integrated energy harvester [6], [7].…”

Monitoring train integrity is a very important topic for economical, management and safety reasons. Knowing the localization, volume and other parameters is very valuable for most train and large industry companies. Current literature focuses on placing many sensors in a Wireless Sensor Network (WSN) around the train wagons, but do not take battery lifetime into perspective. With the increasing interest in industrial Internet of Things (IoT) applications, the connectivity and battery lifetime are very important parameters. In this paper, the vibrations measured on train wagons are analyzed in order to find the most optimal trigger point to wake up or to put the WSN in a deep sleep mode. This way, a large amount of power can be saved and extend the battery lifetime significantly. Furthermore, several Received Signal Strength Indicator (RSSI) measurements were performed to find the optimal Tx level and antenna topology for communication between different wireless sensor nodes on the train wagon. The proposed measurements show that an inexpensive accelerometer and a prefabricated antenna are perfectly usable in the WSN. RF measurements on the brakes results in an average Package Receive Rate (PRR) of approximately 92 % and an Average Received Power (ARP) of around −83 dBm starting from a Tx level of 4 dBm.
