- bluGill 3y agoPTC generally is designed to fail safe, so it will stop the train if something might be wrong. Nothing is perfect, but everything has a compromise and strong trains have a lot of negatives - they cost more, use more energy (read global warming as it there is normally some non-clean energy in the mix).
