Add GTFS to a Network Dataset only generates a walking service area

I'm using the Add GTFS to a Network Dataset toolpak to do some transit-based accessibility analysis. Basically, I'm trying to generate service area polygons from a set of "home" census blocks to determine precisely which other census blocks can be reached in 45 minutes of pedestrian+transit travel. Everything seems to be going fine until I solve my service area analysis layer: it solves, but generates a set of polygons that only appear to cover the distance one could walk in 45 minutes. It appears not to include the transit system at all.

Ideas? Is there a way to check if this is actually what's happening?
