Third Day in a Row Expo Line has Stalled

What is going on?

On my early morning commute, seemingly all week, the trains have not worked. On Wednesday or Tuesday, a train stalled at 29th Station for 15 minutes. The next day, the train came to a stop at Edmonds and didn’t move for 5 minutes. And today, as I write this, a train has stalled at 22nd Street Station and I’m stuck at Metrotown.

Is it normal for this to happen this often?

I’ve been late for work all week and my boss isn’t gonna believe that the train was late again…
