The invention discloses an independent lining trolley for anchorage holes/opening holes of double-track tunnels of special railway passenger lines. The independent lining trolley comprises a formwork assembly (1), an arch center widening mechanism (2), a bracket assembly (3), a center line adjusting mechanism (4), a gantry assembly (5), mechanical support mechanisms (6), a lifting mechanism (7), a traveling mechanism (8) and other auxiliary structures. The left side and the right side of the gantry assembly (5) are respectively connected with two sides of the formwork assembly (1) by the mechanical support mechanisms (6), the center line adjusting mechanism (4) is arranged on the top of the gantry assembly (5), the arch center widening mechanism (2) is arranged above the center line adjusting mechanism (4), and the bracket assembly (3) is arranged above the arch center widening mechanism (2) and is connected with an arch of the formwork assembly (1). The independent lining trolley has the advantages that the independent lining trolley is convenient to mount and detach and good in concrete appearance quality, and the cost can be saved.
