To stop the clips breaking under stress I actually cut the lip on them off to
start with. This provides enough "give" to enable a long bladed knife to be
inserted to cut/split the glued pillars - marked with red
(http://www.brickshelf.com/gallery/whoward69/Monorail/parts/2881r_glue.jpg). If
you attempt this, release the straight branch first, then the curved branch,
then the 4 areas at the top of the picture and finally the mass of red at the
bottom. You will probably find it easier to remove the internal mechanism as it
becomes accesible as this gives more space to work.
As the problem was being caused by the lever in the curved branch I omitted this
on reassembly - the point sit at the entrance to a siding so a train should
never attempt to run through when set the wrong way.
Re-assembly is quite straight forward, but I ended up using liquid glue around
most of the baseplate so I suspect the point will never come apart again!
