Draft copy tool
The copy tool copies a train to a global clipboard. It copies the Line number, Routing code, inside text and outside text. It copies the kinds of wagons in the train and whether they are flipped around. Pasting with the copy tool will conditionally flip the train such that 'your front' of the train, rather than the absolute front of the train, is what is output. The new train is oriented to travel forward with the placing player's view. Conditons are: - Multi-unit/push-pull train (= has locomotives on both ends): Never flipped - Locomotive-hauled train (= has one end with a locomotive): Flipped so that the locomotive is always at the front. If the locomotive points long hood forward, it will still point long hood forward. - Rake of wagons (= has no locomotives on ends): Flipped according to which end of the train the player copies from. If the player is towards the back (wagon out of train divded by total wagons > 0.5), then the back becomes the new front. If the player is towards the front, no change.master
