Piko has the molds from MDC and these are 1/32 scale. Unfortunately one can not always tell which ones are the 1/32 rolling stock. Aristocraft was mostly 1/29 but the Delton molds were 1/24. I know the original question was LGB VS piko, but one should be aware of some other 'oddities'. My Aristo rolling stock is just as good as LGB.
