On top of Columbia being a terrible station for transfers a big issue is the train frequency limitations caused by having a train turn around within the service tracks, Expo is already too busy to allow this.
Also, distance covered by individual trains for one 'complete trip' doesn't really matter, any routing configuration delivering the same capacity will result in the same train running distance and hours.
