This leaves the logger to switch the mill and the interchange, swapping
loads and empties (logs come up from below on flats or skeleton cars, loads of lumber go out in boxcars). There's a fair amount
of switching required to get everything in proper order (and some giant hand action between "sessions" to move log loads).
The logger moves empty flats down the hill via the switchbacks and hauls
loads back up -- the added reliability of making the uphill shoves with loaded cars is another nice benefit of siting the
logger below the mainline.
This little layout would certainly benefit from more length to make the
switchback more plausible, but even in this space offers an interesting display with a little operation as an added bonus.
