Demonstration video of locking frame

Over the weekend I constructed a simple locking bar mechanism which is operated by a servo which locks and unlocks the levers. The operation can be view in this Youtube clip. I think the basic mechanism could be expanded to cover a larger frame without too much difficulty.

David - your point lock lever should normally be in the 'pulled' position in the frame. The point should only be released for operation after releasing the lock. The starter should not be pullable unless the point is in the normal position and the point locked. The shunt signal should require the point to be reversed, but should not require the point to be locked.

I think that all depends a lot on the manufacturer of the frame and the region of the country where it was installed. I think having the FPL 'normal' in the frame as being locked was common in some places. Probably a question best asked of one of the signallers on this forum.
