Metro North Railroad 153.2975 and 153.3425?

I happened to come across these two frequencies 153.2975 and 153.3425 and was curious as to what MNCRR uses them for. They don't look like they are in the AAR Railroad band.

Thanks

After doing some research I found out that these frequencies along with others will be used for an in-house wide area trunked radio system that will be used by various support services.
