Units as far as the eye can see! Well, at least to the beginning of the curve. 3 helpers were added to the already long consisted, stalled S401 at Mance. Every unit but the head end of S401 had either an over heating problem or turbo issues, one unit could not make the grade. The helpers for an eastbound coal train, the 3 units up front, had to be cut at Manila to help out S401.
