You CAN cut the track, if you want to. It's no biggie to do that. I used a Dremel but a simple hacksaw would be fine too.
But, you don't HAVE to cut the track! Just use an insulated rail connector. Or even just leave a gap.
I detailed how I did mine in this thread: https://ogrforum.ogaugerr.com/t...09#70693071014791809
