Insulated joints are used to isolate sections of track for signalling purposes. The fishplates on the sides of the rails are made of a plastic material to prevent shorting of the two sections of track which they hold together. A plastic material (in this case it's yellow) is also placed in the joint where the rails butt together (a gap is left for this purpose). Note the different coloured 'spring clips which clamp the rails to the sleepers (red and blue), the red one is the standard clip and the blue one is a 'left handed' version of it, used in this case to avoid damage to the insulated fish plate during installation or removal.
