    Fig. 13 shows an end view of the second temporary single-line operation with a view of the rear in the degradation direction of the second removal train 37 arranged laying car 35, which is equipped with a manipulator unit 41 for laying in the ridge region 11 to be arranged tubbing segments 36 and on both sides of the Track 2, 3 lying separate working track is displaceable. The stable construction of the otherwise remaining during the expansion of the tunnel 18 permanently in the tunnel 18 laying carriage 35 more typical than a steel frame construction continues to serve in the area of the expansion shield 6 as protection for the temporary double-rail operation and the temporarily single-track operations.
    14 shows, in a schematic plan view, the next method step following the second temporarily single-track operation according to FIG. 11, FIG. 12 and FIG. 13 with a temporary double-rail operation in which trains 22 on the tracks 2, 3 run, while the Alttunnelgewölbe 19 is stabilized and secured in the now unprocessed mining area 29 as a transition region of the Altlichtraum 30 in the new light chamber 31 through the inner locking plates 12 and the outer locking plates 13 with the attached thereto Brustverbauplatten 17.
    It is understood that in addition to the above-mentioned fuses in the mining area 29, an anti-theft device and a head protection can be done by shotcrete and / or rock anchors.
    Fig. 15 shows in a side view corresponding to the illustration of FIG. 4, the device according to the invention immediately before the recording of the temporary double-rail operation according to FIG. 14 before moving the Aufweitschutzschilds 4 and the Ausbauschutzschilds 6. From Fig. 15 it can be seen that after the dismantling of the Alttunnelgewölbes 19 to a tee length secure the inner locking plates 12 and in particular the outer locking plates 13 the mining area 29, while the anti-Aufweitschutzschild 4 and 6 Aufweitschutzschild are still spaced by the tee length of the Alttunnelgewölbe 19.
    Fig. 16 shows in a side view corresponding to Fig. 15, the now after interaction of the walking mechanism 9 and the feed cylinder 10 to the tee length in the axial direction in the dismantling direction on the Alttunnelgewölbe 19 offset anti-swerving shield 4 and the corresponding staggered Ausbauschutzschild 6.
