I did a search for Schleich figures. All I get is animals.....
While animals (farm and wild/zoo) do form a large part of Schleich's range, they have an interesting and often useful figure selection too; farming figures, horse riders and grooms, forestry workers with chainsaws, vets and zoo staff, that sort of thing. They also do (did?) Wild West figures and a whole range of Fantasy figures (Wizards, Knights, Princesses and Dragons etc) for those with more unusual railways.....
They are a little bit larger than regular G scale figures such as Preiser, Prehm and Scenecraft, as they are nominally 1:20 rather than 1:22.5-1:24, but this is not enough to worry about if you are careful how you mix them in your scenes - plus of course they are near-perfect for the 1:19 scale often associated with 16mm.....
