I thought these were happening across the English regions but as a separate project by different teams and so will happen at different times.

I'm sure someone mentioned that there are only two teams working their way through all the English regions. There was a slowdown during summer which was perhaps due to higher levels of annual leave.

Regions also have different equipment upgrade requirements, so not all will have the same project timescale. They also don't know what unexpected things they will find when starting the work.
