I would appeal to him to take one lesson from the 1950s and 1960s, that is, to do nothing that is irreversible. We have heard from this side of the House about the permanent way being taken up in certain areas of the country and houses built upon it, foreclosing the possibility of reopening those lines. It is important that if there is a necessity, for financial reasons, to close, alter or suspend service, in all cases where it is possible it should be ensured that this is a reversible process.
