Sir – I too have fallen victim to the popularity of Thornhill park-and-ride while trying to catch the Oxford Tube to London.

I have given up trying to find a parking place at Thornhill and now park at Redbridge, get the park-and-ride bus in to Gloucester Green and have to pay about £7 for a taxi back to Redbridge late at night.

This is very unsatisfactory and I hope the council soon considers the urgent need for a large extension to the Thornhill car park.
