Genesis 4-6-6-4 Challenger

Can someone explain to me the difference between the Union Pacific fan trip version and the UP museum with oil tender that Athearn is offering in the 4-6-6-4 Challenger??

Thanks!

I’d like to know that, too.

this is on the genesis website:http://www.athearn.com/Genesis/challenger/challenger.html

UP #3985 Double Chimney Smoke Stack • Closed Cab • Oil Tender • Silver Smoke/Firebox

UP #3943 Double Chimney Smoke Stack • Closed Cab • Coal Tender • Silver Smoke/Firebox • Smoke Deflector • Wood Tender Deck

UP #3977 Double Chimney Smoke Stack • Closed Cab • Oil Tender • Gray Paint Scheme • Smoke Deflector

3985 is the last running UP Challenger used for fan trips (last one was to the SuperBowl in Houston )

3977 the gray paint scheme and smoke deflectors suggests that it was used for passenger trains, like the grey paint FEF by Rivarossi but look at thiese pictures I found from the prototype:


there is no gray paint scheme and there are no smokedeflectors!
all this for a mrsp between $529,= and 599,=
