I would think so, from every part of the supply chain it would make sense to use the same segment size, grout, rail method, even manufacturing yards if they're on a train network. But I believe a lot of TBM dig themselves into a not so shallow grave and stay underground: it's expensive to remove them. They drill a headway off to one side and stop like a sad loco in the thomas the tank engine books.

They probably would need major refurbishment anyway, right? Anything that is of value is stripped anyway, and.. the cutting shield is lost (but... who knows, maybe not, as that needs a lot of serviceability anyway, maybe the valuable stuff is removed even from that?)
