| This model was the original SLC prototype and contains the same inversions as the standard model. This prototype was intended to use three, ten car trains. This arrangement had some troubles and the trains were shorted to seven or eight cars shortly after being built. While these models have three trains, only two are ever simultaneously used. What became the standard SLC was adapted from this design allowing for ten car trains. |
