Hornsby is getting a shiny new SSI, so if one processor dies, the other 2 keep
on going.  Ringwood, AFAIK only has a single WESTRACE, so if it dies, everything
is disarranged.  WESTRACE installations in NSW are actually duplicated, so the
failure of a single WESTRACE unit doesn't bring everything to a screaming halt.

I guess NSW Signal Engineers must have a bit more clout over the Accountants
than in Victoria. |-)
