Those clamps look like G scale fish plates, and are obviously home made.
Looking at the point, you might be able to slot the rail back into the chairs marked with the yellow circle, by
carefully bending back the plastic.
The one marked with the red circle where the chair has been 'removed'? Well the slot in the sleeper nearest is the one for the LGB rail-joiner tab. The tab will help locate the rail in lieu of the chair, so IMHO is repairable. You could always add an overclamp type of railclamp for belts and braces. Not sure if the one seen is of that type though.
I've had to do it on the odd R1 point myself. Fiddly, but feasible.
With care, you should get a useable working point, albiet slightly damaged....
