1925–1927 Over the ridge, backwardsCez hrebeň, cúvaním

In Czechoslovakia the Orava line was joined to the Kysuce forest railway on the far side of the watershed. The connecting section, 10.5 kilometres of it, was built in 1925 and 1926 and crossed the Beskyd saddle at 939 metres. The slope there was too steep to be taken in curves, so the line was laid as a series of reversals: the train runs up one leg into a dead end, the points are changed behind it, and it backs up the next — cheap to build, slow to work, and there are five such points on the crossing. The combined Kysuce and Orava forest railway reached about 110 kilometres of track by the late 1920s. The village itself was officially called Erdódka from 1927.V Československu spojili oravskú trať s kysuckou lesnou železnicou na druhej strane rozvodia. Spojovací úsek dlhý 10,5 kilometra postavili v rokoch 1925 a 1926 a prechádzal Beskydským sedlom vo výške 939 metrov. Svah tam bol príliš strmý na to, aby sa dal obísť oblúkmi, a tak trať položili ako sústavu úvratí: vlak vyjde jednou vetvou do slepého konca, za ním prehodia výhybku a ďalšou vetvou cúva hore — lacné na stavbu, pomalé na prevádzku, a na prechode je takých bodov päť. Spojená Kysucko-oravská lesná železnica mala koncom dvadsiatych rokov okolo 110 kilometrov koľají. Samotná obec sa od roku 1927 úradne volala Erdódka.
