Thank you Permanent Way Institution for this video, I have been following the progress of the Colne Valley Viaduct and the method of construction as a retired builder, and this is a great walkthrough of that and has given me a great understanding of it. Thank you all concerned with this presentation.

What's the forecast lifespan, and standard deviation on the prediction, for the match-cast segments, the epoxy bonds, and the internal and external cables?

Misalignment I understand is a current ongoing problem

According to Boris Johnson HS2 is to have a 100 year lifespan (yes, agreed it was Boris Johnson who said that). That doesn't mean some parts will have to be maintained and replaced.

That's true. It depends on what bits are in question. Signalling systems usually have 20 year serviceable life (mainly due to reliability and availability of spares), track is way less and OCR wires tend to be less due mechanical forces. However, most of the civils construction should exceed a 100 year lifespan.
