The trainspotter in me enjoyed reading John Bull's dissection of the Christmas travel woes incurred as a result of otherwise 'normal' festive engineering works. For those outside the UK and insulated from this local news, thousands of trains and tens of thousands of passengers experienced horrendous delays and cancellations at one of London's key railway stations as a result of engineering works running over.
