To challenge your brain cells whilst eating brussel sprouts and watching James Bond or the Queen or whatever on the telly, the Moseley Railway Trust proudly presents the Christmas Quiz. Using the awesome technology of Google Earth, we have satellite reconnaissance photographs of a number of locations of interest to those knowledgeable about narrow gauge railways. All you need to do is identify the places. Simples. The first four are a gentle warm-up exercise, with the fifth being rather more challenging. There's no prize, but if you want to check your answers, get in touch here (Meerkat-obsessive CMEs need not apply). I'll publish the answers and Part Two in a few days.
