This week's "Sonic" Moment of Calm features one of those things which up close is often a little overwhelming, but if you're far enough away, quite soothing.
RNZ Concert's Bryan Crump certainly thinks so; he was in a park in Sydney recording birdsong when a freight train gatecrashed the scene.
Crump thought it was just far enough away to create the right atmosphere.
If distant trains are your thing, try this one out in your own time.
