Jolimont Station is playground for the rat. Robust bodies romp about in ivy-trailing cuttings, their presence noted at bins. Introduction of deadly rat trap houses near signal-posts has not reduced the population. They wiggle under fences, enjoy how halogen lamps transform new passenger shelters into bright theatres of the mundane. JCDecaux advert-scrolls fail to attract attention like a well turned-out rat on his way to dinner. Sightings of rats at Parliament Station suggest they network tracks of the old Loop; research is intermittent. Lonely passengers halted at April train windows cheer up at visions of the rat rummaging autumnal leaves.
