Hello EJB, yes the Monorail's other parts work good and no issues, just those Junctions fail to operate.
I wish that I could get a contact with the original Creator of this Disney Stuff and be able to upgrade his Parts, but there is no contact response, email still seems to be good but he does not respond.
I have a Large Airport in my Custom Map with the Monorails running to all of the Terminals, looks great and is fun to see them.
Cheers.
