I had been looking for S-scale figures. Several companies make them, and they are fantastic. However, they are generally $4 to $6 each. So, when you want to make a scene that has lots of figures, the cost can really add up. Also, I wanted to have figures on our club layout, but there it is easy for a figure to magically "disappear". From the S-scale Yahoo group list I learned about M.T.H. RailKing figures, part #30-11043. These are flagged as "O" gauge, but they are perfect for S-scale. This set contains 120 unpainted figures.
I decided to buy a package and see if they truly are compatible with S-scale. There are four different standing people in the package (as well as several different sitting people). As you can see with the S-scale ruler, the tall man is a scale 6'6", the shorter man is 6'3", the woman is 5'8", and the child is is 5'2". That is probably ever so slightly too tall for an S-scale purist, but it is definitely close enough.
These are the four seated figures I found in the bag.
