I think Dutch public transport is not half as good as it could be for such a rich and densily populated country, and it's still going downhill.
Main problem, as I see it, is that in the '60s and '70s there's been very little investment in railways, everybody thinking the motercar would be the perfect solution for all transportation needs. Now that the country is turning into one great traffic jam, instead of putting lots of money in a long-delayed expansion of the raiway network, it gets privatized. And, as the British found out, you don't privatize a monopoly like that overnight without massive problems (at least The Shambles Formerly Know As British Rail shows some signs of improving). What's worse, the department that runs the train and the one that maintains the tracks have been uncoupled /ubbthreads/images/graemlins/wink.gif so there's no more preventive mainternance on tracks and signals, resulting in plenty of delays. There's also talk of closing, or selling, all unprofitable lines.
