I have current experience with building interlaced turnouts in G1 using Cliff Barker's combined sleeper/chair units- similar to what you are designing- and I've found it difficult to thread rail through a lot of chairs before the resistance requires a lot of force. 100_020900_040000000.jpg If you print the keys separately then the rail will just drop into the chair jaws from above. Insert the tapered keys (narrow end first!) and then break/cut off the sprue. Warning: if used outside then glue the keys in place otherwise the birds will think that the keys are seeds and eat them!
