Good grief, you're right. But there are 2 baseplates per sleeper.Of course if there were 365,000 clips at 2 clips per sleeper, there should be about 182,500 sleepers.Except there are typically 4 clips per sleeper, one on the gauge side of each rail foot, one on the field side.

There are three crossing loops from 1850m to 2050m, not including the turnouts. Also a few wheat sidings and a siding for track machines. Strangely two of the 1100m long wheat sidings is signalled almost as if it were a crossing loop, albeit with catchpoints and motor points.
