Why is it that when they finally go for clockface (good), IE have to make it so incredibly inflexible (bad)? S-Bahn lines in Germany (pretty much the equivalent of the DART here) are clockface with different patterns peak and off-peak. Why can the DART not be clockface every 30 minutes at night, clockface every 15 or 20 during the day and clockface every 10 minutes during rush hour? Is that so difficult?
