Subway

In the bowels beneath the city I lie 
A sunken passage between all points on the map
Hollow, but with the memory of life
Vermin travel through my veins
Foraging through the disregarded scraps dropped from life above
The rare plant can be spotted
Illuminated through the cracks in my roof
A complex series of interconnecting halls make up my form,
and these halls hold vast darkness.
They hide underground, intermittently breaching to the surface for air.
Machines used to carry life through my arteries 
like blood cells carry oxygen.
After all, movement is what brings me life
But now my halls are empty
And my heart beats no more.
