Yep. My thoughts were about some kind of wedge-shaped actuator (solenoid-driven?) that could do the mechanical locking, whilst external configurable logic (cheap diodes and gates) could do the decision-making process according to the locking chart. It's not the Tim V 'full-monty' of course, but an approach that recognises that most people's track plans will evolve and change.
1. What make?
2. What is the lever pitch?
3. What extra space is required if you put two banks of levers side-by-sise?
4. What is the maximum throw (i.e. last hole out) of the levers as supplied?
The original interlocking question was just to find out the level of interest in that - definitely non-commercial.

That was another one, look for the recent article by David Barham, Winter 2011 Journal.The Merg article on a locking lever frame, so far as I can recall, seemed to involve locking and unlocking the whole frame, which didn't feel right at all.
