You may want to check the electrification standards for earthing and bonding. Generally, two pairs of double joints are installed maximum train length plus a margin apart from each other to avoid traction current propagation in fault conditions. The reason for two set is if one fails and train is bridging the other set, large fault currents can appear in unexpected places.
Another anomaly is the yellow line on platform edges. Many people assume it is to do with protection from trains. It is actually a minimum distance from conductors. Not sure if it is the IEE Wiring Regs or a law elsewhere.
