I can't say I disagree. The term "plate" was initially used in wood car construction, so there was little confusion with "plate" steel.

Also the member across the bottom of car framing is almost universally called a "sill" (side sill, end sill) because in invariably spreads the load and transmits it to the bolsters. This differs from common architectural usage, where the "sole plate" of a stud wall, for instance, serves to space the studs, but doesn't actually distribute their load, and so isn't actually a sill, and therefore isn't called a sill.

Now that we're through the definition of "plate", the distinctive feature of the piece that both CV and CN used is that it's a steel pressing, rather than a length of standard section structural steel.
