[quote user="CSSHEGEWISCH"] [quote user="TooeyB"] You know what would be real cool?  Since the heritage concept has been a winner everywhere it has been tried, why not have them produce a generation of passenger locomotives with the sheet metal resembling  the old "E" series of the 40s and 50s? <div style="clear:both;"></div> [/quote] The compound curves of the bulldog nose are expensive since they have to be shaped virtually by hand.  How much of a premium would the builder charge for this sort of option? <div style="clear:both;"></div> [/quote] The compound curves are shaped by die forming in a press.  The dies are custom tooling which adds cost, but special tooling is also required for large radius straight bends found on many locomotives.  There are also compound curves on smaller parts of most locomotive bodies.  The hand work on EMD F and E unit noses was adding the fillet radius at the base of the headlight casing.  I understand that detail was made by placing bondo and hand grinding to form.  The headlight casing was a separate formed steel part that was welded into a hole in the nose form, and then the fillet radius was hand-made around the casing over the weld.  There is a finanacial incentive to eliminate compound curves because it avoids tooling cost, but there are still several of them in the EMD rendering of the new passenger locomotive shown here.  If you try to eliminate compound curves, you end up with that edgy Russian locomotive look.
