Some listings seem to be of dubious merit, this one included. Pretty much every town in the North has a stone railway viaduct somewhere, is there something particularly unique about the Huddersfield one other than it being the location of the first write-off of a Pacer*?
Corners being cut during construction (as alluded to a few posts back) certainly isn't unique, given the number of tales I'd suggest that Victorian building contractors were pretty much expected to commit these acts of fraud!
*=on second thoughts, for that it shouldn't just be listed, it should be canonized!
