Berlin Europe Railway Network

The Berlin Europe Railway Network (BERN) or the Berlin Europa Eisenbahn Netzwerk, is a system of rail that is planned to cover much of Europe and beyond. The project was started by the German Empire's Kaiser and quickly expanded into a large concept. It will link many cities including Finse (Capital of the Danish Empire), Moscow (Capital of the Union of Soviet Socialist Republics), Belgrade, Berlin (German Empire), Paris, London, Edinburgh, Madrid (Capital of the Communist Empire of Greater Spain), Lisbon, Athens, Istanbul, Ankara, Copenhagen, Chisinau, Warsaw, Sofia, Vienna, Budapest, Bucharest, The Hague, Brussels, Rome and Zurich (Largest city in Switzerland). Much of the engineering expertise and materials will come the German Empire as the creator of the plan as well as Berlin being the BERN Corporation Headquarters and a hub for most of the railways. This project is extremely large as it will require a cross-English Channel tunnel, many bridges in Denmark and a tunnel under the Turkish Straits.

BERN USSR
The BERN lines from the USSR borders to Moscow(specifically, those going through the cities of Warsaw, Kishinev, and Kopengagen, among others) are joint-managed by BERN USSR (German: Berlin-Europa Eisenbahn Netzwerk für die Union der Sozialistischen Sowjetrepubliken; Russian: Берлин-Европа железных дорог для Союза Советских Социалистических Республик, tr. Berlin-Yevropa Zheleznykh dorog dlya Soyuza Sovetskikh Sotsialisticheskikh), a branch of the BERN that is technically owned by the workers to not violate the USSR's communist ideology, and the Soviet National Railway System. The part between the borders and Warsaw & Chisinau are more managed by the BERN representatives than the SNRS, but the rails from Warsaw and Chisinau to Moscow are managed much more by the SNRS. The Soviet government has secretly agreed with the Germans to try and spirit some of the profits from the railway to them in return for a few perks and benefits. This is not a widely known fact though, and it is effectively unknown in the USSR.
