In the Fastrack modular layout guide ( http://lionelllc.files.wordpre...oad-manual-ver-2.pdf ), they illustrate back-to-back 072 switches used as crossovers (on page 33). I was curious how reliable this combination is in regards to derailing while moving between the parallel track. They also show a siding using an 072 with an adjoining 072 curve, thus making a small S (reverse) curve. Has anyone tried this and does it run smoothly?
