Of course. The people who organise these things must do the best they can within the limits of the resources available to them. Railway engineering works necessarily disrupt someone, somewhere, sometime and Bank Holidays are reasonably considered to be the best time to minimise that disruption. I'm just trying to point out that less disruption isn't the same thing as no disruption. You may not be able to reduce the disruption by very much, even on a Bank Holiday. And it's a pity that the quickest rail route between Edinburgh and London will partly be closed over a long distance on probably its most in-demand weekend of the year, thus maximising public dissatisfaction and minimising public esteem for the project. As a regular railway user and enthusiast, it's frustrating to feel that the railway is actually doing its job better than many lay people would perhaps feel inclined to give it credit for, but could still improve a lot and majorly improve its PR with just a few tweaks in things like project planning and technological improvements, and by making itself easier to deal with, by orders of magnitude, when things (inevitably and unavoidably) go wrong - but that's another story for another thread.
