They probably can be, but Caterpillar tunneling is completing its wind down after this project ends. Caterpillar had a buy-back on them, but doubt that will be exercised now. The Sheppard Subway TBMs ended up in Russia.
Historically, other manufacturers have refurbished competitors' machines, so a contractor could buy them and have someone else fix them, likely for a BRIC-country project. Turkey for example, is a huge market for used TBMs these days.
Is that due to the repair costs (and safety standards)? That it is cheaper for us to buy a new machine than the constant repairs on an older machine? Or do we buy shiny new things for the press release?
