But there are 12 in total, right? So in the last several years you've only had 12 additional inspectors added to the system, when rail operations have gone up significantly, including profits--and the usage and the accidents.
Has there ever been an analysis in terms of what would be the optimum number of inspectors that would be appropriate, especially if the usage of the track is increasing, and there's a new mandate, say, for example, from U.S. security, which is one I gave an example on? Has there been that type of analysis?
