I think the Swanage Steam Railway would be a great steam route addition for people who like steam locos or diesel locos. Swanage Steam Railway branches off just after Wareham in Dorset and runs all the way down to Swanage The Swanage Railway is a railway branch line from near Wareham, Dorset to Swanage, Dorset, England, opened in 1885 and now operated as a heritage railway. Occasionally during summer months SWR Class 159 are seen on the Swanage Railway
