ADD SOME FUN.
This alternate approach adds about an hour to the route, for small groups. While the route is fairly straightforward, the rappels themselves have awkward starts and are not suitable for beginners.
Russell Gulch requires an additional permit to your Subway permit, has a group size limit of 6 and a daily quota of 12.

The Business
Traipse down Russell Gulch, occasionally wading through knee deep pools or scrambling over logs and rocks. The first rappel is soon found--100 feet (30 m) over a pothole and to the edge of a pool. Expect wading up to waist deep in all these pools. However, canyons have been known to change from time to time, so the rappels very well could end in swims.
All rappels in this canyon are bolted.
Continue downcanyon. A second rappel of 100 feet (30 m) is made down a steep wall and into a shallow pool.
Continue downcanyon. A third rappel may require some effort to get to. Steep slabs can be downclimbed on canyon left, or a short, dirty rap made from a large tree. Rappel the overhang to the slab below, about 100 feet (30 m).
Continue downcanyon. The last drop ends in a large pool near the confluence of Russell Gulch and the Left Fork. There is no convenient anchor, and the pool is often a skanky swimmer, so it is rarely done. From the top of the drop, follow a small trail up and left through the woods that leads to the bottom of the steep, sandy gully that is the normal Subway approach. Descend to the canyon floor, and continue down The Subway.
Zion's Subway is a wonderful, beautiful canyon, enjoyed by many people in several different ways. I made a run through on a recent weekend to re-locate the first anchor, bolted this spring but not in the best place (from my point of view).
