Kewaskum interesting pictures

Someone donated some postcards from the 1900's and included in this collection are pictures of a railroad wreck, as well as a bridge washout, taken at the turn of the century.  Not sure if the washout was the cause of both the concrete and the railroad bridge problems, or if these occured on separate occasions.  If anyone has knowledge about these photos, I'd like to add that information.
It's amazing to look at the last picture and see the tracks just hanging in the air.
