Not always. There are/were plenty of instances where there were in fact three
point levers involved e.g. Avenel had a couple. It is hard to describe but it
works along the lines of an interlaced pair of crossovers with their own point
lever and the connecting bridge track with its own point lever. The double
compound at Flemington Racecourse is also an example unless they have rearranged
the point levers but seeing as how it is rocker locking, I very much doubt it. No
depending just where they were located you might two or three lock bars but it
depends on the way the interlocking was arranged.
