GP might realize sooner or later that they need larger security margins, for when unexpected things happen; like really having to go to the toilets, spilling the coffee they just made, etc.
They can shift their daily schedule e.g. 30 minutes earlier and peacefully drink their coffee at home. They also should eat something at home or on their way, because hurrying in a cold morning with an empty stomach is not good. Source: personal experience. I did that for months as a student until I passed out one day in class.
If they don't like waiting for the train in the cold, they probably can find a warm place near the station, and wait there a little.
