After an ops generation, color codes are automatically shown on all cars and stations in the switchlist, and car id's are also displayed on the cars.
To turn all color codes on or off: use View > Color Codes on the main menu. To turn car id's on or off, use Train > Show Car IDs. You can toggle the
display of Car IDs on moving trains by using the checkbox Preferences>Trains>”Turn off while moving.”
To highlight a single move: you can interact with the switchlist window for a more detailed look at your assigned job. Click to select a row in the switchlist window, and it will turn
off all color codes EXCEPT the one on that car and its destination. This gives you a handy way to click down through the list and see where each car is located and where it's going.
To turn all color codes on: click any empty spot on the layout or the bottom of the switchlist window. This cancels any single selection and shows all colors for the switchlist.
