On my Pi Zero WH I have two displays, one set to platform 1, and the other to platform 2. If a train on platform 2 stops has a short calling pattern and the one on platform 1 has a longer calling pattern, the one on platform 2 will show all its calling points and then loops back to the start but also causes platform 1 to do the same rather than continuing to display its calling points.
