My layout previously was set as a hybrid track able to do both digital and analogue racing.  As I recall the main thing needed was a large 4 pole dual throw switch for you to easily swap between the 2.  As had been mentioned earlier you just need to make sure for using cross overs to do so in pairs.  Having said that, one of my cross overs was modified so it could quicly swap out with a straight piece.  This being good for Mr Billy No Mates to have a long circuit covering both lanes for a single lap time attack :)
