legend of Zoro

folks,
I just rented the DVD of this movie and it ends up with what may be a narrow gauge engine and train wreck. XCan any of you fill me in on what engine it was, a 4-4-0 and where it was? Perhaps down in Mexico?
the wreck and explosion was out of a computer I think. I hope the engine will be there to run another day.
One interesting mistake was a scene where they threw a janney coupler which did not come into use on the railroads for many years after 1850.
Also the switches they threw were not stubs but much more modern ones with points.
I think it was a fun movie with a steam locomotive thrown in also!
