AAR said US total rail traffic continues to show mixed results in monthly rail data, and that impacts from Hurricane Sandy can be seen in decreased traffic for the latest week.

"The fundamentals of US rail traffic remained roughly the same in October as in recent months: weakness in coal, remarkable growth in petroleum and petroleum products, a slight slowing of growth in intermodal and autos, and mixed results for everything else," AAR said.
