Latest iteration. Overall size has been reduced to 9.5x9.5 feet (there was a lot of empty space and this will make it even easier to fit into a new room if we ever downsize our home). Min radius is still 21.25", all switches are Peco's "large". There is enough of a feeder to the union station such that the main will not be fowled by a train backing in. Not sure if the coach yard is really functional in terms of making up a train.
