There was plenty of other stuff going on, platforms were being surfaced, poster boards erected and so on. S&T engineers were fiddling with wires.
So, it's all looking good. Of course, there's lots of finishing work to be done, and then the small matter of electrification to deal with.
I have been checking my notes for the previous re-modelling of Huyton Junction which was in 2007 when it was changed from a traditional double junction to the simplified double junction we had until last week. This was completed in a four day Easter blockade and my logs show the trains running normally on the Tuesday morning.
