Here's the 624 with her two new mates coupled to her tender--

Together slumbering, to spend eternity on this patch of soil.
Did I say eternity? Gosh, that's an awfully long time. Forever, even.
On the other hand, there is always the future chance that the 624 gang will move on. New display locations, serving new purposes...but always still around, remaining as familiar faces to Region Rats everywhere. Serving as pleasant nostalgic reminders that the railroads once were a very large deal in NW Indiana.
