I guess the good news is it looks like only one car went on the ground. The only thing I see is in this photo, the flanges on the two visible wheels are either sheared off or were worn very close to condemnation limits... http://thundertrain.org/AMT21derail-wheels-010610-1058am-6.JPG

I'm no judge of flange heights but if it's of any use, the UK standard is 28mm to 36.5mm.

Standard US flange height is 1 inch (25.4 mm)
I have recently had to go through the EU standard on wheels. After wading through a complexity that looks like it is written so as to include every possibility of wheel and tread ever used in western Europe, you find a statement that, "The base profile is that obtained with a flange 32.5 mm thick and 28 mm high.
