Isolating a section of already-ballasted track?

[RobertInOntario]

In some of my railway magazines -- mainly the British ones -- I've seen them refer to something like a pair of cutters (almost like wire cutters except these are for track) that can be used to snip the rails of HO track instead of using a saw. Has anyone else used these or know if we can purchase them over here?

For example, see this site (<!-- m --><a class="postlink" href="http://modeltrains.about.com/od/track/tp/Model-Trains-Toolbox-Track.htm">http://modeltrains.about.com/od/track/t ... -Track.htm</a><!-- m -->) about half way down the page.

Thanks.
