I think you could use one Tortoise machine with 5 bell cranks. You would use one bell crank for each set of points and one to move all 4 with one Tortoise machine hooked up to it. It would take some design work to locate all of the bell cranks and I don't know if the extra bell cranks would end up costing as much or more than the Tortoise machines.
