A September 4, 1975 letter to the editor in the Korea Times:
At that point the Seoul subway (line 1) would have been operating for a year. One wonders if the writer had a chance to ride it at rush hour. Certainly, even on line 9 today, trying to get off the express train during rush hour sometimes requires "brute force" just to be able to step off the train and not get pushed back inside by those rushing to get on (and pushing those in front of them).
