Caught a long delayed train instead of the one that I was meant to catch so I thought I’d get to London early. But further delays due to signal issues resulted in long delays on the way into London. But got there in the end. The train was 47 mins late according to the announcements. I was only 20 mins late.

Anecdotally the ULEZ is a success. London smells better. The traffic moves more freely. Pollution has reduced in London and I wonder if the pollution outside London has reduced. Pollution rises into the atmosphere in London and then comes down in Oxfordshire. Has anyone measured this?

In last weeks election the Conservative Party made much of the ULEZ. Unfortunately the primacy of the car still exists for a lot of people and is considered a vote winner. To me health and the environment trumps-why do we still think that poisoning people is acceptable?
