Navigating large sessions can be hard work if you’re not used to it. Once the edit window gets deeper than your screen you have a few choices, you can hide some tracks, you can reduce the size of the tracks or you can scroll up and down the edit window. Going straight to the track you’re interested in can be done by using Scroll to Track Command but there is a faster way using the Tracks List in the left hand sidebar.

Just Command+Control click (Start + Control on a PC) on the track you want in the tracks list and the edit window will scroll to that track - easy!
