No; the line is conventional single track through those tunnels, with points at both ends.
Not any more. It's ordinary single track now.
Bog-standard normal railway line
Can be useful for threading two roads through where there's only the physical clearance for one...But I'd imagine the removal of old Gauntlets would most likely have been ordered by the HSE, as - Without a lot of specialist detection and interlocking equipment being installed - There's no way of preventing two trains entering the same section from opposite ends and colliding. With Gauntlets, each "pair" of rails can still be electrically isolated from each other, meaning that track circuits wouldn't be effective for protection.Suppose it allows two lines to remain in place without having to have junctions for the narrow strecthes of track
The track circuiting controls are common through the area of interlaced track.Can be useful for threading two roads through where there's only the physical clearance for one...But I'd imagine the removal of old Gauntlets would most likely have been ordered by the HSE, as - Without a lot of specialist detection and interlocking equipment being installed - There's no way of preventing two trains entering the same section from opposite ends and colliding.

That said; Gauntlets take up less space than two roads as we've already determined...But surely a mile of Gauntlet would cost no less than a mile of dual-road because the former still has the same quantity of steel and requires specialised sleepers...Is that right?
Interlacing only removes the need for the S.
