ELO, Lyrics:
Train of Gold.

I saw her there from across the street, she was dressed in black
And when she moved she moved to a beat, like a Cadillac
She rode a train, train train train, a train of gold

She was a woman of suspicious ways, never saw daylight
And in her room she sat and passed the days
And she'd creep out at night
She rode a train, train train train, a train of gold

Chorus: Train of gold, train of gold
It took me so long to find out I was wrong
Now I wait for her in the night

Looked through a window saw a velvet sky, a shade of green
A violin was playing soft and sweet, like it was a dream
She rode a train, train train train, a train of gold

Train of gold, train of gold
It took me so long to find out I was wrong
Now I wait for her in the night

Train of gold, train of gold
I don't believe her, it just couldn't be her
I can't get it out of my mind

Jeff Lynne
From the 1983 LP, Secret Messages.

Facts:
In the chorus of "Train Of Gold" from Secret Messages is an odd squeaking sound, that is actually someone (perhaps Jeff) saying "train of gold" and heavily distorting the sound by twisting the knobs on playback and speeding it up. For years, the sound was thought to be an odd scraping of something across the string of a stringed instrument (e.g. guitar, violin, etc.) until you listen closer.
