Thanks for your interest in working on fixing up the MBTA data in OSM -- but please don't make such a big change without discussing it first! We settled on using the short form for the network (and mostly for operator) -- please revert this unexpected and disruptive change until we have time to handle it (e.g. updating PTNA config ( https://ptna.openstreetmap.de/en/config.php?network=US-MA-MBTA ) among other things. You can discuss it here: https://community.openstreetmap.org/t/automated-edit-proposal-fix-mbta-stop-position-nodes/101680/5
