I recall reading about the local transit department which had gotten some fancy accelerator card to help with route searches, ie when a customer wanted to go from A to B, which busses, trams etc to take. Can't recall if it was "just" a bunch of FPGAs but it was a big-ass PCI card. Some years later I tried to find this story again, and to check if they still used it. Turned out they had ditched it after just a couple of years. As memory sizes had increased, they could just precompute all possible routes for the next day and keep them all in memory...
