What is "item size" for Tomytec power units?

[scott]

HS lists an "item size" for the Tomytec power units, but it's not clear if that's the size of the package or the size of the unit itself. From some of the sizes, I'm guessing that it's the size of the box, but then how do you know the size of the unit.

 

(FWIW, I"m trying to see if I can fit one of these into a non-Tomix railcar whose own "power unit" frame is about 13cm long.)

Thanks, Bill--that's exactly what I needed.
