This is what it sounded like to me:
Chorus (x 2):
I'm coming to you on a heatwave
No matter how long your love takes
I'm coming to you on a steam train
speeding out of the night again
(night again) x
[instrumental break]

Is there something sacred that you believe in?
{Is there a castle to the sand?} - unclear
I'm approaching with an open heart
I'm coming to you right from the start
And now are you gonna let me in?
Chorus
