Friday 13th April proved to be "lucky for some", amongst whom were the Swanage Railway and John Bunch whose ex-Southern Railway class U Mogul no 31806 was the first of the railway's steam locomotives to venture out onto the main lines on a magnificently-successful test run from Swanage to Wareham, Weymouth and Yeovil. This was the first time on the main line in the preservation era for this particular locomotive, built in 1926 as express passenger K class 2-6-4 tank no A806 "River Torridge" (it's classmate no 31624 ran on the main lines in the late 1990s). As is well-known, the "Rivers" rolled and were all rebuilt as tender engines without names whilst further engines were built as Moguls. There are two more Maunsell Moguls now at Swanage, the other U and the sole member of the N class. We see no 31806 at Wareham and then storming up to Eversholt tunnel and finally reversing onto its train at Yeovil Jct.
