Archaeologists in London have begun digging up some 3,000 historic skeletons including those of plague victims from a burial ground that will become a new train station, the company in charge said. Crossrail, which is building a major new east-west train line in London, said the dig near Liverpool Street station was being carried out on its behalf by the Museum of London's archaeology unit.
