I threw together a working wye junction in Trainz and I noticed that when the "on screen help" is turned off via the menu(ie. no directional arrows at the turnouts/switches) that when the mouse cursor is placed over the lever of the turnout the green arrows appear and allow you to switch the turnout. Then the arrows dissapear when the mouse is moved away from the lever. This obviously means you do not have to activate the "on screen help" to switch the turnout! I know most of you know this but I thought it is a very cool feature to note for new users. And it does not have to be a turnout that your loco is directly approaching to switch the turnout.

This also means if you have a hump yard, it is not necessary to have the help directional arrows of the turnouts busying up the screen while selecting tracks to sort the cars.

The fun continues...
