People who are rushing may need the speed advantage of walking up escalators, which is faster than walking up stairs. I’ve caught a long distance train with less than a minute to spare, which had I missed it, would have delayed my journey by an hour before the next train. It shouldn’t have been that close, I left with plenty of time to get to the main railway station via the Underground, but sometimes multiple subway lines have issues and you get cascading failures that leave you with no other choice but to run up escalators or miss your transport (especially if it avoids having to buy another train/plane ticket)
