I bought a round-trip ticket for a short train trip in the Netherlands, paying full price. Later I asked a colleague if there are discounts of any kind. Yes, she said, as long as you travel after 9 a.m. I assume this illustrates peak-load pricing, so I asked about traveling in the evening rush hour. It turns out the discount is good any time after 9 a.m.—there is no peak-load pricing for evening rush.
