The running tunnel is 9 ft diameter : the running tunnel between

FSVO "all". Look at the pictures. There are clearly some single track

9 ft is a good deal larger that many site construction tunnel or even
final tunnels e.g. sewer or water tunnels that have construction

Where the tunnels are 9ft that would be true.
