An often raised problem for people with the Magnorail cyclists is when the cyclists throw back their knee like a Chicken or Emu when they lay down. Laurina from Western Australia brought this up again so here is the explanation I gave her.
The solution is a small pin or piece of plastic inserted into the bicycle frame to restrain the legs from doing that. The photos show where this pin on some models comes preinstalled but also where to attach a pin if you are having this problem. Why it was not consistent across the range I don't know.
The pin stops the thigh part of the leg from reversing its action. I spoke to Loek (the inventor of Magnorail) and he couldn't remember why they stopped inserting the pin but that aside, it is a fairly simple fix.
Clyde has been involved for many years with the Magnorail system having initially built his own layout "Echo Lakes" featuring two concepts using the Magnorail System. In 2019 he rebirthed his layout as Crater Lake featuring four Magnorail circuits plus an Ho3 train line around the perimeter which is now the Magnorail flagship for exhibitions.
