Now that is a lot of concrete ties! Each (full) stack looks to have 90 ties. A very quick (and extremely rough) estimate indicates there are probably over 40,000 ties here, ready to be used! At 20" between each tie (about right for EMU commuter rail), these ties could cover 12 miles of single track or 6 miles of double track. Actually not all that much when you think about it.
