You need to use the gradient tool - you will find it at the right side of the row of linear object tools. One tip - the closer to the arrow you are, then the easier it is to get the exact height you need. Use your mouse to drag the arrow to the correct height. Joining a side track to an existing track is accomplished easily if both the section you are joining from and the section you are joining to are at the exact same height and all relevant sections are level. Don't forget to click on the Snap to Track option in the bottom left panel. Excess height arrows can be eliminated by highlighting them (they turn to red) and then clicking on the delete button.
