Post office railway reuse
a TBM won't care if it has to dig the whole
tunnel itself or theres a small tunnel already there , it will take more or less the same time. It won't you know. If it doesn't have to dig the middle bit, it doesn't have to do the work. That means less work needs to be done. And that means it takes less power. And that means that more power is available to put into the work it does do. And that means its more efficient, and it finds that work easier Plus why inflict a windy route on a new rail line when for high speed it needs to be as straight as possible. If its going to have to stop every few hundred yards for a station, it hardly matters whether high speed is possible or not. Its not that windy anyway. |
