Wildly annoying morning

I sat on a train and waited at Copenhagen central station, already 4 minutes late, this morning, when it was announced that a train had stopped with technical difficulties further down the track in Valby.

Smart as I am I thought that I'd just jump on an S-train and get going, and I saw the right train waiting for me two platforms over, so I ran.

And as I ran down the stairs I heard the train I'd just left 20 seconds earlier start.

Nothing I could do about that, so I ran on, appearing on the right platform just in time to see the train I wanted disappear in the distance.
