This and the related articles cry out for some illustrations. Well done illustrations would be far more useful than photographs for it.JimD 20:57, 2004 Jun 21 (UTC)

I agree, though at the moment even some photographs would be an enourmous improvement, as there's not much of a physical description of the devices -Lommer 02:05, 22 Jun 2004 (UTC)

Tunnelling/Tunneling[edit]

The concurrent use of two variant spellings annoys me. The article is called "tunnelling shield". Could we use tunnelling throughout? Everybody got to be somewhere! (talk) 22:28, 11 March 2010 (UTC)

Diameter[edit]

Used for what sizes of bore diameter? --Helium4 (talk) 05:12, 21 July 2016 (UTC)

I have added the diameters of some of the early bored tunnels as examples. Paul W (talk) 17:50, 26 July 2016 (UTC)
