I've been playing around with JMRI - when I build a train to visit my switching layout, it wants to pick up every car that is already set out, even if those cars are still Loaded. How can I tell the train build to only pick up the cars that need to move that session?
Never mind! For anyone just starting out with JMRI, I'll recommend the excellent blog by David Haynes. Part 1 is at https://model-railroad-hobbyist.com/node/10834 and got me on the (... ahem) right track.
Glad you were able to answer your own question. I'll add another recommendation for anyone involved with JMRI. Join the JMRI users group: https://groups.io/g/jmriusers You'll be interacting with the actual developers of JMRI as well as other expert users. The group is a fantastic resource. - Jeff
