DC: 70, and higher rolls get better results. Failing this roll will lock it in for next turn - the DC will be lowered, while rewards, including additional ones, remain the same. Guaranteed Rewards:
As the Eisenwerke expands, production capability increases, improving equipment reliability and availability.
The Type 60 Kriegslok, if this option is taken with it, will have additional bonuses to reliability and production speed.
The Eisenbahn-Artillerie-batterie "Kronprinz William" will form, with four 203mm railway guns, if the Type 60 Kriegslok option is taken with this one.
The KPG will gain a minor influx of new members, as will the GNVP, and, luckily, the GDP will too.
Needed to gain a fourth "Industries, Agricultulture and Infrastructure" option slot, which is opened by also taking two of the following options: The New Germanian Economy, or Agricultural Revitalization, or The Class 60 Ragnite Locomotive Initiative.
