@tzhs Good question! When these (and other) units were new, that was the normal procedure - back-to-back, so they would not have to turn them for the run in the opposite direction. But, as they aged and became more unreliable, it seemed to make sense to have them both facing forward so that the second unit could be switched to lead, if necessary. That's my theory, anyway In this case, I actually heard (on my scanner radio) the engineer talking to the conductor in the train if he could get to the second unit to reset some control because it wasn't loading and thus it was taking the lead unit too long to make speed after a stop. If the second unit was facing backward, there would have been no way for the conductor to get into it.
