Although I've never seen any signs of a railroad at Rivendell, it seems that it's the perfect place to film a train disaster. A new movie is currently being filmed called "Tangiwai", for NZ tv, and today we arrived at Rivendell (Kaitoke Regional Park) just in time to watch the film crew throw bits of train off the bridge down on the river bed, in the hope of creating that lovely "smashed" look.
Take a look for yourselves - I taped it.
Tangiwai Traincrash at Kaitoke
It's not the best footage but it's fun to see, I hope.
