You can see the S1 operating in both my LNER Robinson locos video and LNER 8 coupled freight videos. Thanks glad you like them.

What an amazing job. I was always too afraid to tackle stratch built stuff, but these models look excellent. The S1 tank (or GCR 8H) is my favourite. It's absolutely gigantic and I love it. I wish someone would make it or the GER A55 Decapod as ready to run one day. But man, these look incredible 👍👍 the booster unit on the rear wheels looks incredible too. I'd love to see it run. The P1 is quite clever with the tender drive too. I don't have any major complaint with tender powered locos, but it's not as good as loco powered I think. Though the P1 made sense, otherwise it would have been a nightmare and let's face it, no-one is going to notice it. It runs well and looks nicely.
