Picture perfect

Dozing off on a rumbling train,
a shrill cooing escorted by a cacophony,
effecting an underwater drum,
pricked me into reality.
Eyelids half-open, cornerning the source,
Driven by a mind tug locked -
Arise? .... What's the hurry?
Then, a voice so strangely familiar,
Tuned into my dreamy waves.
Wide awake now, straightened to behold,
A face something wrong,
The beauty of light blocked,
Yet a soul undeterred,
Selling wares, head upraised.
A carriage of no profit,
But a carrier of pure gold.
