Canterbury had a railway link to London before 1850, engineered along the Stour Valley from Ashford, a relatively flat line which needed few road bridges, over or under. However, there are a number of level crossings, two of them in central Canterbury, capable of holding up road traffic for minutes at a time in queues 100m and more long.
Sad to say, most cars and motor vehicles (but not the local buses) have their engines left on at this time, wasting the drivers’ money in fuel burning uselessly. That we might say is their problem, but it’s everyone’s problem when the air on St Dunstan’s Street is so often polluted above safe levels; it’s everyone’s problem when greenhouse gases are unnecessarily emitted into the atmosphere to add to global warming.
Please think about switching off your engine when traffic grinds to a halt at a crossing or other hold up.
