I may get a little time to work on the layout this weekend, but Saturday afternoon, we go to my daughter's house. ?Our granddaughter is graduating high school and we have a party. ?Last weekend, we went to Atlanta for a family visit, but I did get a few hours off and went to the Southeastern Railway Museum in Duluth. ?I took lots of photos, including some very up close and personal photos of the B-End details of a couple hoppers. ?they had a 4-4-0 there with PISTON rod valves and what looked like Walschaert valve gear. ?the darnedest thing I ever did see. ?I expected slide valves and no external valve gear for a 4-4-0. ?I must assume this was retrofitted by a previous owner and did not come from the factory this way.
