Definitely the larger sister to Anna, and with clear Zillertal heritage, Helene uses the same unique slip eccentric reversing mechanics, burner arrangement, and regulator/lubricator. With the relatively large boiler and and fuel tank I have yet to let Helene run 'till she drops. The rear truck is stock LGB, including the loop and hook, and an LGB logo and part number are molded into the plastic. Interesting that Beck had access to those parts as I imagine that LGB would be rather unfriendly to the idea of anyone including LGB parts on a non-LGB locomotive these days.
