Yes, but as I was saying to Mr. Hubbard, the Railway Safety Act prevails with respect to fumes released into the environment.
Recently, the department came to an agreement with the rail company. All locomotives are subject to the U.S. regulations because that is where they are built and manufactured. So this act does not grant this power.
With respect to vibrations, I should clarify that the vast majority of complaints received by the agency, and even by the department, pertain to noise. However, where there is noise, there are vibrations. I think that the two phenomena are closely linked. In my opinion, if we can resolve the noise problem, we will, to a large extent, be resolving the vibration problem.
