Hi,

todays top engiine of the Amtrak is the P42. My question:

Some say P42 some say AMD103. What is correct is it the same engine?

The designation AMD-103 was the basic design that includes the P32, P40, and P42. Possibly other variations.

Actually, I don’t think that the P42 is THE number one engine of Amtrak. I think the Acela Express is the number one today (yes, I know it is a “trainset”, but it acts as one engine).

To answer your question, however, the previos post is right.
