I've tried to see if I can somehow change the state of things like switches or signals...but so far without luck. Can that only be done in the paid version? If not, then how?

Thanks in advance

Looking forward to playing with trains...yay!

Hello,

Select signal or switch with the mouse (left button) and use the space bar to switch.
Sorry, English is from Google - translater ...

Many greetings, Lutz

Thanks, Lutz - you just saved my day! :-)

you can also add a switch and/or signal to the board and click the "connect" button in its settings to assign it to a point

also in "event control", you can get it to switch automatically when a train passes through, reaches a certain part of the track or after a timer
