Our monthly architecture rides continue to be well-attended, varied and inventive.
There was no running out of steam in November 2007 as we went on a tour of railway station architecture, inspired by the re-opening and re-invention of St Pancras.
As well as the great termini we examined lesser known gems like the lavishly Italianate Battersea Park Station and the disused Waterloo Necropolis Station.
Engineering necessarily took a more prominent place in this ride than in previous ones and as we assessed sheds, ribs, bowstring trusses and ridge-and-furrow glazing healthy debates were had about where engineering ends and architecture begins.
The 1960s built Euston had few defenders but it did offer a fine railway-centric pub for lunch. Testament to the interest of the ride were the numbers who stayed with it till after dark, finishing with a lament for the abandoned Eurostar terminal at Waterloo.
December offered a briefer jaunt on a tour of Christmas illuminations. On a Saturday afternoon we slid through the feverish crowds of shoppers in the West End, and finished with mulled wine at the Bankside Frost Fair. Top marks for lighting imagination went to South Molton Street, Covent Garden Market and the Oxo Building
