The low level is buried 34m underground. https://www.crossrail.co.uk/route/stations/liverpool-street/
it was originally buried so that it could connect up with the Metropolitan Railway (today's metropolitian line on the London Underground)
this was so that in 1875 the Met could use the mainline railway station as terminus (whilst their own was under construction)
