When running multiple trains in the simulator, after some time a random track is coloured yellow, but there are no train present in the fields, this situation will block all other traffic in this area of the layout.
By move the mouse pointer across the train field (red frame in the image), a hided train appears (See image 2), but train is not active.
Any tip what my be wrong?
Again the cause of error my own fault. The previous trip was missing a block. By using the logbook the track to fault was found. Again GREAT software, but also complex and easy to create a fault which in turn can be difficult to find. Currently running 10 trains by simulator and 0 errors :)
