Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill

Our goodwill, all of which pertains to Rail North America and Rail International, was $78.0 million as of December 31, 2016 and $79.7 million as of December 31, 2015. In the fourth quarter of 2016, we performed a review for impairment of goodwill, and concluded that goodwill was not impaired. For 2016 and 2015, changes in the carrying amount of our goodwill resulted from changes in foreign currency exchange rates.
