Problem with attach / detach / transfer functions

[r.roeterdink]

In certain situations, the attach / detach / transfer function does not work, trains will not attach or do not get permission (clear signal) to approach the train.

[r.roeterdink (r-roeterdink)]

The problem occurs in particular for actions including the player train.
The cause of the problems is the re-assingment of train number 0 for the player train.
For player train, the ORG-AI number (original AI number allocated to the player train) must be used for all data relating to attach / detach / transfer actions.
In all checks relating to these actions, there must be specific tests on the OrgAINumber for the player train.
