Similarily in Germany the DB (Deutsche Bahn) was also privatized in the 90s (100% owned by the government tho). Since then half of all points/switches were removed since they’re expensive to maintain. This leads to many trains being late, which propagates through the entire railroad network. And half of the revenue of DB comes from businesses other than transporting people because the latter isn’t really profitable. Infrastructure isn’t profitable, that’s why mass transport should be nationalised (again). Just like roads.
