Lithe electric tigers
Midsections thick with swaying bodies
Glide along, converging, diverging, a dance along the tracks
Hiss past Vauxhall and whoop into Clapham
Doorways gasp and heave out people
disgorging commuters as plenty more swarm
round their panting mouths,
waiting like fidgety flies for a carcass.
Rickety rumble from the Junction jungle
Ferrous fauna in a railway rainforest
Trains make these rails
sing with life.
