Early in the morning

the trains already smell -

the air thick with human odour

that open windows fail to dispel.

The malodorous fug a fruity blend

of smells man-made and natural -

a vast array from pleasant perfume

to others more diabolical.

A few top notes punctuate

the background smell beneath:

beery breath and garlic;

blocked sinuses and bad teeth.

Bodies emitting clues to diet:

the raw fish of sushi,

the spices of curry and stir fry,

and ubiquitous coffee.
