In real life, a transfer table is used to switch monorails between tracks, but most monorail lines are only one way or two way the whole length. Usually the transfer table is at the workshops or depot.
On TRS, special junctions are used. They are just like normal train (or tram) junctions, but the 2nd track leaving the junction is invisable (or at least on the maglev routes on TRS).
Oh and if your making a model of Disneyland in Los Angeles, as far as I know there wern't any junctions, but I may be wrong.
