The railroads may not have been given a choice. All the govt has to do is say that inspectors feel your current operational level and volume is in violation of safety and send a list of new requirements and just about an business would comply. A lot of business owners are hesitant to take strong political stands because which political group is in charge constantly changes so you don't want to piss off either side too much. The best bet is to try to fly under the radar while trying to appear to stay with the main crowd overall. THey have PR departments to help them with that.
