In the daytime, what am I?
In the hubbub, what am I?
A mass of iron and of steel,
Of boiler, piston, throttle, wheel,
A monster smoking up the sky,
A locomotive!
That am I!

In the darkness, what am I?
In the stillness, what am I?
Streak of light across the sky,
A clanging bell, a shriek, a cry,
A fiery demon rushing by,
A locomotive
That am I!
