St Pancras International Railway Station is the London terminus for Eurostar and one of the biggest railway stations in the United Kingdom. 

It's not an exact 1:1 representation of the building as its extremely hard to achieve with the scale of minecraft but its as close as I can get to it, its taking a long time though as I have very little time to do it but its getting there.

A schematic/world save will probably be uploaded when its finished but for now there's some pictures (excuse the quality, I only have a poor wornout laptop, hopefully a friend will render it eventually)  :)
