Foreign currency translation negatively impacted revenues by $123 million in 2012. This revenue performance also reflects lower volumes due to soft end markets in metals and commercial construction. In Rail, revenues grew 17 percent primarily due to the volume of equipment deliveries under the large order with the China Ministry of Railways, which is now nearing completion. Industrial revenues increased 15 percent, driven by strong energy markets early in 2012.
