I went to the Great Central Railway at Loughborough on the first day of the "Golden Oldies" gala at the Spring Bank Holiday weekend. This week will feature some of the very old locomotives on duty while I was there. I have, at last, been playing about with RAW and all of this series utilises RAW, CS3 and Topaz.
Planet was another early steam locomotive built in 1830 by Robert Stephenson and Company, again for the Liverpool and Manchester Railway. It was the first locomotive to employ inside cylinders, and subsequently the 2-2-0 type became known as 'planets'. The replica was built in 1992 by the Friends of the Museum of Science and Industry in Manchester and appears at the event with the permission of the museum.
As with the Rocket replica this locomotive also ran return trips to Quorn and back during the weekend. You might enjoy this short video of Planet and Rocket out on the tracks.
