Starts with the loco taking on water at Gwaai, where the fire would have been cleaned as well. Note on the drivers side (the right) the rails stuck in the ground with wires strung along them. This is the signaling cable. The white ant like the insulation covering the wires and eat through them when underground, causing shorts. Other things to note are electric lights behind the gauge glasses, the fireman and drivers comfortable seats and the thin glass frame by the driver (and fireman's window) to stop cinders and insects hitting people in the face.
