two twin-tunnels from Limmo to Victoria Dock ear-

lier this summer.

Crossrail will complete its rail tunnels next year

when tunnel machines Elizabeth and Victoria, cur-

rently in Whitechapel, reach Farringdon in central

London. Crossrail’s new rail tunnels are 83 per cent

complete and the project remains on time and

within budget.

AndrewWolstenholme, Crossrail Chief Executive


“Huge amounts of planning go into every

tunnel drive, and this one is no different.

We are deploying some of the world’s best

engineering talent and machinery to safely

build these new tunnels.”

Ellie has already successfully completed a tunnel

from Pudding Mill Lane, near Stratford, to Stepney

Green. The tunnel machine is 150 m long and 7.1 m

in diameter and is staffed by teams of 20 people.

The concrete and steel tunnel segments are made

in Chatham, Kent and transported to Limmo by river


Joint Venture Dragados Sisk is constructing the

eastern tunnels between Pudding Mill Lane and

Stepney Green, Limmo Peninsula and Farringdon,

and Victoria Dock Portal and Limmo.

Jessica Going Strong

Crossrail’s tunnel boring machine, Jessica, has

completedanewtraintunnel fromLimmoPeninsula,

near Canning Town, breaking into Victoria Dock

Portal in east London.

The 1,000 tonne machine completed her 900

metre journey in just 9 weeks, travelling as far as

41 metres per day. It is Jessica’s second Crossrail

tunnel drive, having already created one of the two

tunnels forming the spur from Pudding Mill Lane

near Stratford to Stepney Green.

With her work completed, unlike many tunnel

boring machines in the past, she will not be buried

in a tunnel. She is to be dismantled, with parts re-

turned to manufacturer, Herrenknecht, for use on

other tunnelling projects.

Jessica is also 150 m long and 7.1 m in diameter

and was staffed by teams of 20 people. Tunnel seg-

ments were made in Chatham, Kent and transport-

ed to Limmo by river barge.

Crossrail uncovers Brunel’s railway


• Victorian-era rail infrastructure excavated near Paddington as part of the UK’s largest

archaeological programme

• Engineering marvels of the Great Western Railway are uncovered for the first time in

more than 100 years

• Remains of structures built by celebrated engineer Isambard Kingdom Brunel for his

Great Western Railway have been unearthed near Paddington in west London.

TBM, Ellie, begins final 900 m drive - the shortest

but most complex tunnel due to adjacent rail

system and the Rive Lee and River Thames
