A megalopolis of engineering.

The new stations on the Elizabeth line are 240 meters (788ft) or longer and sometimes nine or 10 stories underground.
“And these are only the most visible manifestations of the vast volumes hollowed out of the London soil to achieve an underground railway bigger and faster than any before, of what was at one point the largest transport engineering project in Europe, decades and billions of pounds in the making, a system more technologically complex, than any outside China” as Mr. Andrew Wolstenholme – the new stations on the Elizabeth line CEO – said.
