The Zoom Tube Tutorial article will help you out with your Zoom Tube. It's tricky, long, and frustrating. You can also try out the Zoom Tube Wizard found on SRB2 Doom Builder; however, you have to manually set the second Zoom Tube Parameters' sequence waypoint number.

Zoom Tube Start and End
You begin by making your 2 sectors that will become the Start and End of the Zoom Tube. For more information, go to Zoom Tube Start and Zoom Tube End. As shown in those articles, they can be on a normal sector or on an FOF. After that, you need to tag both of these sectors to a Control Sector with the same tag. The Linedef Type needs to be 3, Zoom Tube Parameters.
Zoom Tube Parameters
The Linedef Type 3, Zoom Tube Parameters, and the Tag is best to be placed on the top part of the Control Sector, to draw out the X Length (speed). If you're going to make a second Zoom Tube, the new Tag needs to be on the bottom part. The Y length determines the sequence number. Sequence number 0 is the first Zoom Tube, so sequence number 1 would be the second, and so on up to 127.
Zoom Tube Waypoints
The Zoom Tube Waypoint determines which Zoom Tube sequence it belongs to, how high it can be placed, and the number in the sequence. The first one of Sequence 0 would have to have an Angle of 0, proving it's the first one. The second one of Sequence 0 would be 1, and so on.
For the first waypoint of Sequence 1, the first one would have to be 256. For sequence 2, the first would be 512. It can go up to Sequence 127, where the first Zoom Tube Waypoint would have an Angle of 32512.
Tips and Tricks
There are times when the Zoom Tube seems to be broken. You start by going on the Zoom Tube Start sector, and make a sudden stop on the first Waypoint. There's a way to fix it:
If you're using Waypoint Sequence 0 (which is the default from the Zoom Tube Wizard), then use a different waypoint sequence number for that Zoom Tube. Waypoint Sequence 0 is unstable.
