I assume this is all hopper car data we're looking at? If so,
what could have caused that burst of hopper cars in July?"
It would be nice to know the data, but unfortunately, this is all I've got. (Hence my comment about looking at this through a straw.) This is indeed all hopper car data - as for the "burst" in hoppers in July, look again at the number of days covered. The "burst" is simply more data points.
