Suggestion: Trains finished at last temporary point should return to manual mode.

Most often my usage of temporary points is moving to far region of map to start new mining site or to expand railway lines.
I click a point on map closer to my destination and wait while my personal train moved where.
When usually I need to manually move the train further, but it doesn't start to be controlled by keys even character still in where.
Train still in automatic mode, even when after several seconds temporary point vanished.

My suggestion - when last temporary point vanished toggle train to manual mode where we can move it by keys.
