There are some things I would like to point out to Bachmann. Post-War #4459 is actually a GS5, not a GS4 like it has been labeled, and #4464 is a GS6, which has also been labeled a GS4. GS6's had 73" drivers, and only one headlight.
Does Bachmann plan to fix these errors to make it the way it should be?
Steam Freak,
The only visual distintion between a GS-4 and a GS-5 is the roller bearing caps on the tender trucks and trailing truck. I would not hold my breath waiting for Bachmann to correct that, but it would be relatively easy requiring only two new parts.
As for the GS-6 thing, you can go to Las Vegas and bet the house they are not retooling for that either.
But you are correct on that being a completely different loco. Different frame length and driver size.

You said turning a GS4 into a GS5 only requires two parts? What are the parts? That way my friend can modify it.
Read what Sheldon wrote you - the correct tender trucks and trailing truck. Two parts. Or, I guess, you can modify the trucks on the model so they look like they have roller bearings.

A recent article in a model railroad magazine tells how to convert a GS-4 to a GS-X.
