I can't comment on when the change over occurred, but, I can help
you get your nomenclature correct. It is not a 'Triple "K" Brake'. It is
a _control valve_ called the "/*_Type K_*/" control valve (more commonly
called a 'triple valve'). The "triple" refers to what the valve does.
That is, /*Charge*/ (the air brake system), /*Apply*/ and /*Release*/
the air brakes. So it is the "K" type, "AB" type, "ABD" type, etc., all
of which we refer to as a triple valves.
