Guy, you are not being realistic if you expect every fire crew to have memorised every road change particularly those made on a 'temporary' basis. All fire engines have GPS trackers and, to the best of my knowledge, use a proprietary sat nav system to get them to incidents as quickly as possible. Is your transport team providing data to London Fire Brigade on LTNs in a format they can use to update their systems and, if not, why not?
