That is Lionel's description of their products, not mine. NEPA is just trying to distinguish between the 2....thats all, nothing more, nothing less.
Thats why I suggested he simply look at the pilots in the first response. All of what you refer to as scale engines have the freight pilot regardless if the term Scale is used in Lionel's description which it is not in the pre Legacy versions.
Freight Pilot on the left.

This shot clearly illustrates the difference very well. The main difference is the vertical compression of the PW 2343 on the right. As you can see (mentioned by several) are the 'squinty' windshields but also the taller pilot and overall lower profile of the older model.
Terrific photo Pete - have I seen that one before?
