This just in from the Lionel updates:
"For Nickel Plate 765's re-release, we've added two nice touches to celebrate her long career in excursion service. The Nickel Plate locomotives were equipped with Mars lights during part of their service career, and 765 has carried this on excursions in the past. So you can have it both ways, we're including an extra smokebox front with a Mars light detail. This can be substituted for the single headlight smokebox front installed. The working Mars Light is in the boiler. Also included with the 765, a certificate signed by the steam crew at the Ft Wayne Historical Society."
That ought to make some Berk fans happy (and fuel the fires of the Big Boy eaters).
