In-Game Chat and Discord
Anyone using MPS will want to chat directly with users online. You can do this directly in-game via the chat window.
To focus on players or private message them you can click on the "Sharing Menu" at the top of the screen and select "Open Player List".
You can also use
DISCORD to chat outside of Trainz. DISCORD allows you to chat in the
mps-general-chat channel or voice chat and share your screen.
