I understand removing overtime, but surely they could have finished one
or more of the stations by now? If so, then any associated workforce
may be able to be used on other parts of the project to not slow that
down any further.

While they all might look identical in their orange outfits, in practice
they have many different skills and are employed by many different
contractors. Some skills/employments may be transferable, but lots
aren't.
