At the Chiltern MR exhibition at St Albans last weekend, Brian Caton was showing a large layout displaying his 00 and 009 live steam models that he has been making for the last 20 years (I'd seen an Isle of Man live steam display before). They are single cylinder and gas fired, controlled by electric servos picking up power from the track. He had several large notices saying that they were not Hornby :-)
