Very interesting, his Overhead is particularly inspiring with his use of what appear to be Twigs on the Return Loop. A not unprototypical arrangement on some of the European lines that were somewhat poverty stricken. It is also interesting to see that his Trolley Wheel works so well without a Swivel Head. But I guess that he knows his pinch points well judging by the slow running in places. Great stuff thanks for posting.
