Hi Paul,
Fundamentally JMRI is setup to move a railcar once per session.??A person would?Build all the Trains at once then print out the Manifests and Switchlists for the Trains and Locations (the ones that have a Local Switch crew).? At the end of the session they would then Terminate all trains.? The program is then ready to start over again for the next session.?
You can move a car more than once during a session and some people do this by Building and Terminating trains in sequence as the session progresses (similar to what you are doing).? The "problem" they run into is that?1 person?is stuck at the computer doing this instead of having a throttle in hand running trains. I?achieve this a little differently.
For a little more insight into how I Build, Print,?and Terminate trains in JMRI_OPS to move a car multiple time during a session read through post #146888 and its associated messages.
Even more things to consider!
