If you're driving a train, you understand there will be delays. However, you probably don't expect that one of those delays will come from a horse who's decided to stop on a bridge you need to cross. That's exactly what happened.
We can all agree that waiting for a train to pass in the middle of town can be really frustrating. Even more so when you're late for something and all of a sudden a train comes out of nowhere and makes you even later than you already were.
