First of all, the NYC may have considered these unit U30B's. As I have said many times, railroads call locomotives lots of thing, some of less than 100% accurate. As we used to say when I sold locomotives for a living, they are their units, let them call them what they want.
None of the NYC U30B's were built in 1966. The first unit arrived in February of 1967. You type a great deal of conjecture, much of it in accurate and treat this as fact. Volume does not take the place of fact.
So what was GE testing if it was not the 3300 hp rating? The carbody configuration? I assure you that I am not basing my argument on Athearn's model.
With any of locomotives I use two tests. If I were going to order parts for one, what would I do? The answer is order parts for a U33B. If I were going to model one what would I base it on? A U33B. Not one thing you have said changes these basic facts. All you have proved is that the NYC called them U30B's! Frankly, who cars what they called them, they were almost dead ringers for U33B's an a long way from then current U30B's
As far as the rest goes, who said anything about the P&LE? Yes the late U25B and the early U28B share the same carbody. The late U28B and the early U30B also share a similar carbody. Nobody is debating this or for that mater, even mentioned it.
Your discussion of the U34CH is accurate on one point, they are based on the U36C (and predate them by almost a year). Beyond that, you are just repeating an inaccuracy that has floated around the railfan community for years. The U34CH was rated at 3430 HP. However, the 170 difference between the 3600 and 3430 was not due to head end power loss. It was due to the fact that GE need to reduce the prime mover's (diesel engine) RPM to give the head end alternator the correct RPM to produce the right cycle. The best the engine could produce at this rpm was 3430. In fact, horsepower for traction could be as low as 2700 hp if pulling a sizable fleet of cars. 170 hp would not have been enough to light and heat/cool much more that one car. Yet the fans continue to accept this inaccurate explanation as gospel. Another example is the often published accounts of Altoona assembling the SD80MAC's. The were painted and tested there but built in London.
As far as the M640 goes, you are missing the point. Even though it was built as and delivered at 4000 hp, CP chose to class it the same as the M636 fleet. This was done by a carrier that generally changes the class for every order of units delivered. You cannot rely on what the railroad calls the unit.
