Working through construction is sometime like a endless grafting project working to get stuff lined up level so your trains don't have to suffer through uneven track that causes operational problem like uncouplings, derailments and other problems.
One of the steps I take before track goes down is hitting the cork with a belt sander to take these variations out.
Case in point from Doswell from the previous fall season (2019)
You can see the high and low spots by just looking, so that tells you some remediation is called for here.
