I've been thinking about trains which will run into St Catherines's Bay, with consideration being given to their length and the number of each type required to operate the day's services.   I've pretty much nailed on the passenger services, I think.  Most trains will spend life as permanent sets, and most will have a dedicated cassette for storage, when not in-play.
