This document outlines Transport for London's challenges in upgrading and maintaining the London Underground rail network to meet growing demand. It discusses how demand is expected to increase 20% by 2020, but capacity increases from upgrade programs may not keep pace. The deep tube lines pose unique challenges due to small tunnel sizes and tight curves. Heat retention in the tunnels is also a major issue. Technology and innovation will be needed to improve customer experience, delivery efficiency, safety, reliability and sustainability as climate change and demographic shifts impact operations. The future vision is described as an "always connected" system providing a "fantastic journey" each time through improved maintenance, operations and customer information.

4. Transport for London (TfL)
• A statutory body whose principal activity is the provision of safe,
integrated, efficient and economic transport facilities and services, to,
from and within Greater London, established under the Greater London
Authority Act 1999
• TfL delivers its services through:
• Barclays Cycle Hire
• Dial-a-Ride
• Docklands Light Railway
• Emirates Air Line – Cable Car
• London Buses
• London Overground
• London River Services
• London Streets
• London Trams
• London Underground
• Taxi and Private Hire
• Victoria Coach Station

5. London Underground
• London Underground is a
network of 11 lines serving 276
stations
• Celebrating 150 years, we now run more services than ever
before
• More than 1.1 billion passengers a year
• Around 4.1 million journeys made each day

6. London Underground - today
Over 4 million journeys/day,
Over 1 billion journeys/year
20 million customers
800 km of track
600 trains
5000
signals
276 stations
402 escalators
13 depots

7. Our Challenge – Demand Forecast
• Demand is up by 24% in 10 years and 61% in 20 years
• Growth is expected to continue – another 20% by 2020

9. Our Challenge – Deep Tube
• LU’s deep tube lines have particular
characteristics which make them unique
worldwide:
– Small tunnels, fixed platform lengths
– Tight curvature
Infrastructure constraints:
Small tunnel diameter, fixed platform
lengths and widths
Line geometry: Deep level, small
single bore tunnels with no side
access, tight curvature, large platform
gaps
Heat retention: Inadequate
ventilation; rising tunnel temperatures
32°C or more in summer
Open sections (‘at grade’):
Extensive non-tunnel track sections;
interworking with other services

10. Our Challenge – Heat
• What goes in, mostly
stays in
79% Tunnel Walls
• Only way out is air
11% Piston Effect
10% Mechanical
Ventilation

11. Our Challenge – managing change
Climate change creates new challenges and
worsens existing problems
Changing customer
demographics
Changing pace of technologies
brings about new challenges and
offers new opportunities

14. Value and sustainability
We want to use technology to minimise the impact we have on
the environment by improving energy efficiency and reducing
noise, while minimising the impact of external factors, such as
weather and theft, on our services.
• Manage the impact of the weather on the operation of our
services
• Minimise the noise associated with operation and
maintenance activities
• Reduce theft from our network
• Improve energy efficiency and sustainability
• Improve asset intelligence and maintenance processes
• Share equipment across the business

16. Delivery
We are looking for new technologies and processes to help us
achieve reliable and safe world class delivery, requiring minimal
closures whilst driving for efficiencies and cost reductions.
• Drive improvements in our people, processes and
technology
• Improve safety
• Improve the reliability of assets and services
• Minimise closures
• Reduce overall costs and improve programmes delivery
predictability
• Improve track renewal methodology
