This involved the extension of the existing line from Sonkovo to Krasny Kholm railway station as far as Ovinishchi, and then to Vesyegonsk.

This was then linked, via Ovinishchi, to the line to Saint Petersberg through the Mologsky passage [ru] at Pestovo.

The plan was abandoned after the creation of the Rybinsk Reservoir flooded much of the area, including part of Vesyegonsk.

Concerns were raised that passenger numbers were very high in summer and the bus services would not be able to cope, and that fuel supplies, as well as cargo transport of mixed fodder and molasses for agricultural producers in the area, were delivered by the line.

[5] There are commuter trains to Sonkovo, via Ovinishchi and Krasny Kholm, which provide onward services to Moscow via Kalyazin, and Saint Petersberg via Bologoye.
