Private geodesy companies have prepared a map on a scale of 1:1000 of the proposed 1160-km long railway from Dalanzadgad to Bayantumen, meant to help carry coal from Tavantolgoi. They consulted the Railway Managing Office often.

Earlier, the Agency of Land Affairs, Construction and Geodesy had prepared a drawing of the railway route as described in the railway policy of the Government.  Its way to Bayantumen from Dalanzadgad goes via Tavantolgoi, makes a detour to Tsagaansuvarga and then carries on to Sainshand, Baruun-Urt, and Choibalsan.
