Most certainly, they bundle multiple sub-projects throughout the affected territory so many things are done in parallel, minimising down time for the train operations.
The only problem is that this adds complexity in planning and coordinating all of this work, which may require overlapping track protection, conflicting movement of equipment and material, and multiple subcontractors and multiple work plans to be vetted and approved. ML is far from perfect at juggling all of this, and there are certainly cases where work falls off the schedule due to preparations being incomplete, or execution being a fail. But certainly, as a strategy, they try to work this way.
