Originally released as a single on Columbia in May 1966. It is based on an earlier song of hers, one entitled "17 Pink Sugar Elephants". The melody and chord structure are near identical:

Many folk wish to know the lyrics to the song, so here they are:

Train Song (Bunyan/Clayre)
Travelling north, travelling north to find you
Train wheels beating, the wind in my eyes
Don't even know what I'll say when find you
Call out your name love, dont be surprised
It's so many miles and so long since I've met you
Don't even know what I'll find when I get to you
But suddenly now I know where I belong
It's many hundred miles and it won't be long
It wont be long
It wont be long
It wont be long
Nothing at all in my head to say to you
Only the beat of the train I'm on
Nothing I've learnt all my life on the way to you
Only our love that's over and gone
It's so many miles and so long since I've met you
Don't even know what I'll find when I get to you
But suddenly now I know where I belong
It's many hundred miles and it won't be long
It wont be long
It wont be long
It wont be long

This song became familiar in the UK, thanks to a most peculiar T-Mobile ad:
