Pictures of this short-lived siding are very rare. Thanks to Ted Curphey pointing this one out. I'm quite familiar with this site, as I lived in a house on the corner behind the cement structure. I had always wondered why the railroad code line rose significantly at this site, as if a road had once crossed the tracks here. This photo proves it did have some sort of crossing. This scene shows the cement processing plant installed here to facilitate the lining of the West Canal nearby.
Google maps street view of this spot today. That's my old house back there.
Satellite view of this scene today. Note the short distance to the West Canal, where the cement was being sent to.
