Hi,Peter, I don't think that the relative speed of these two great engines matters anymore,just that they are still around for future generations to see,feel and smell,my hat goes off to all the people who keep these old ladies running and on track for us all to enjoy,by the way did anyone see a programme on tv about a little Indian narrow gauge railway that had a couple of old mountain steam engines that they had restored and kept running for tourists to ride on,I do believe that the engines where made in Birmingham in about 1905, just goes to show that love of steam it is not just an Angle-Saxon thing and is universal........Ray.
