From Chicago, and Railway Age's Rail Insights Conference and Expo today, June 7:
William Vantuono, Editor-in-Chief, Railway Age: What has been Union Pacific's progress with PTC?
Rob Knight, Chief Financial Officer, Union Pacific: We have been aggressively pursuing completion, with eyes on that 2018 completion date. It's all very complex, and expensive. When finished, we will have spent $2.9 billion on capital up front, and we've already spent about $2 billion, which shows you how far along we are with it all. But it's been costly, and we’ll need to recover our investments somehow.
