Jerry - the most sensible (and both easy, and simple) way is that the carfloat arrived before you start your shift - so it is there when you clock on- and sails after you have finished - so it is still there when you go home and the next shift has taken over.
You can move it about to simulate sailing, using rods or levers under the layout - but whether it is worth the added complication is up to you - or have the float on a roll-about tea trolley-type arrangement - using more than one if you want to make life complicated.
I made life difficult for myself by building an HO layout that fitted into a Shoebox ( for a competition, and to see if I could do it!) - if that would interest you see http://rmweb.co.uk/f...ngleferry wharf , and also http://www.rmweb.co....her-exhibition/ - this float moves sideways and is part of a "reversed Inglenook" - where the car float forms the sidings (which move), and the head-shunt remains stationary ( the reverse of normal practice) You can also find it on Pages 73, and 78a of http://www.Carendt.com. I've also attached an article from a way-back MRR regarding shift work operations which might be of interest, and/or use to your operations.
