Smelly Train Poem by Tin Can

A train guards nose picks up many smells.
How many do you suppose...? Read on and I'll tell.
Early in the morning it is the aerosol spray.
Some wash with the can, avoiding delay.
Following quite soon is the smell of perfume.
Detecting the fragrance can take till noon.
Then the pain of eggs eaten on the train.
Travellers who do so, should simply refrain.
Next there's the smell that's simply the best,
I must mean, 'LUNCHTIME...! ' How did you guess...?
The aroma of hot meat pie and fresh ripe fruit,
Filled sarnies on rye, aromatic Italian prosciutto.
And after all has been eaten, the booze is due,
Along with the smelly burp, and a rush to the loo.
The methane released can be quite vile,
As it fills not only the carriage but also the aisles.
And the late night trip has that whiff in the air,
Of vomit. Spew and sick that drives you to despair.
Finally..., at times, the trains simply do pen and ink.
But don't take my word...! What do you think?
