According to
Wikipedia:
The name Flying Dutchman has a convoluted history. In common with many steam and diesel engines such as the LNER A1's and BR class 55 Deltics, the Flying Dutchman was named after a famous racehorse, which had won both the Derby and St. Leger in 1849. The racehorse was in turn named after the famous Dutch Admiral Tromp.
My first thought when I saw the OP I was thinking of the steam train running back in Victorian Times and I actually thought the name was playing with the words flying and dutch...
