▎ 摘　　要

NOVELTY - The railway has a graphite rail composed of a deep underground railway tunnel graphene round wall (9), an underground railway (10), an underground railway graphene conductive line grid (11) and an underground railway graphene train (12). The deep underground railway graphene conductive line grid on an upper part of the underground railway graphene train is provided with a deep underground railway graphene communication system (13). The underground railway graphene train is connected to a deep underground railway graphene communication system through a conductive wire. USE - High speed information deep underground railway. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a high speed information deep underground railway.
