Very nice work on both sets. As noted, the figures that don't come from Lionel (or K-Line) that are sold by far eastern suppliers are on the big side. The best figures in terms of fit in these interiors are those that were produced for MTH under the Railing brand. You can still get large packs of the unpainted figures; the sets of painted figures are harder to come by and not cheap. I don't think that MTH issues the sets any more but MTH O scale passenger cars come fitted with them.
