Based on the picture in that article, looks like it was the Northbound train at this intersection:

I always cringe when I hear people getting hit in the NE as there are a few places where one train can pass and you could start crossing thinking its all clear, but there is another train coming the other direction at the same time that is mostly blocked by the one that just went by (ie NB train clears intersection, but is blocking view of a SB train not quite at the intersection yet). It doesn't appear to be the case here. Wonder if we'll hear any more about it.
