Transcontinental railroad and the bessemer process
Both presidents were conservative in their policy.
The main difference would be their attitude towards the foreign trades.
President Harding was a determined in secluding United states from foreign trades which ending up in worsening relation with other nations in europe.
President Coolidge on the other hand, is was very open minded about the foreign trade, but he still had to face the negative effect from Harding's decision.
It helped them find and attack German planes.

The Eastern Front or Eastern Theater of World War I (German: Ostfront, Russian: Восточный фронт, Vostochny front) was a theater of operations that encompassed at its greatest extent the entire frontier between the Russian Empire and Romania on one side and the Austro-Hungarian Empire, Bulgaria, the Ottoman Empire and the German Empire on the other. It stretched from the Baltic Sea in the north to the Black Sea in the south, involved most of Eastern Europe and stretched deep into Central Europe as well. The term contrasts with "Western Front", which was being fought in Belgium and France.
It is mostly for the protection of individual rights
