Interestingly, many TBMs are left underground forever, as it's often more expensive to disassemble and remove them then to just abandon them.
- Animats 11y agoThat's only done when you have a meet between two TBMs coming from opposite directions, and there's no way to get them out. Only for very long tunnels is that necessary. For most TBM jobs, you get the TBM back when it breaks though at the end of the job. After refurbishing, they're good for another job.
