Thank you for the question.
The answer is a little bit complicated, because we have a large number of people in the department who perform oversight functions. Amongst those are inspectors who are actually classified as inspectors and perform inspections primarily, but other activities as well. Then we have engineers who perform inspections too. I can tell you with absolute certainty that we have increased our staff in all modes. I believe the number is 1,600 total people who provide oversight functions, which include the inspection function. We don't track specifically by the classification of inspectors anymore.
In rail safety, for example, we were running normally at around 102 positions associated with oversight. As of April 1, 2015, we were at 122 oversight personnel in rail safety. As I said, that includes some other types of positions aside from pure inspector classified positions, but they do take part in the oversight process. We've had a net gain of 20 in rail safety alone. Certainly we've been in an active recruitment process across all the modes, and I can give you more details, if you'd like.
