They work with the municipalities and the urban developers to make sure the proximity guidelines are respected, to make sure there is enough distance between the railways and residences, and that any development and growth around railways is done safely so that we can minimize the risk of noise and trespassing incidents. That's what we are doing.
I can't speak to specific cases, because those would have to be addressed specifically by the railways on a one-by-one basis involving specific examples. The CTA is also engaged in this. If there are noise complaints, residents obviously have an opportunity to go to the CTA, and then there are standards and procedures put in place.
