Another ‘catch-up’ post, from last September when the group made its first visit to the Derwen Fawr railway. As well as a raised running loop, this links to a portable Inglenook shunting puzzle. This caused a fair amount of head scratching with members trying to arrange the wagons to the order determined by counters drawn at random, within the constraints imposed by the length of the sidings… Meanwhile on the loop plenty of trains ran – both live steam and electric.
