Isolating a section of already-ballasted track?

[RobertInOntario]

Yes, I know that kind of cutters (german term is "watenfreier Seitenschneider", con not find an English translation). They are great to cut rails prior to installation but not after installation.

The advertising reads "Cutters will leave a smooth cut on the end of rail without any burrs or rounded edges". That is correct that one side is cut very clean but the other side is like cut by an ordinary cutter. It will also extend the length and you get a lot of trouble doing it at an installed track. This drawing is a nice explanation:

Thanks, Reinhard! So I'll only consider these, then, when building new layouts. Looks like I'll still have to patiently use my Atlas saw or buy a Dremel for my project.

Cheers,
