Innovation on Thameslink
• Using new products equipment and tools to reduce costs
and create efficiencies
• Often teamed with headquarters, maintenance, or another
programmes
• Most have a large engineering content and the
development of a new product
• Often involve product acceptance and changes to ways of
working
• Need to flexible, adaptable, thinking out of box
• But still supporting programme delivery

Example of a successful project - New
CCTV technology for London Bridge
• Use of mega pixel technology to reduce the number
cameras needed for London Bridge station.
• The reduction of cameras produces reductions in brackets,
power, cables
• The like for like saving for the London Bridge installation is
£1m (25%) but the big saving is in maintenance – circa
60%
• Project Manager’s role was to gain acceptance by the HQ
CCTV group and NR Head of Security and have the
standard changed

Mobile Maintenance Unit
• The MMU is a train with a
workshop, stores, messing,
worker transport
• Self contained train for installation
and maintenance
• Moving green zone – work force
protected
• Realisation is that MMUs will
radically change the way we plan
and manage our site work

Mobile Maintenance Unit – Status
Continued
• Second variant
– Enables slim-line gantries to
be used
– Efficiencies in installation and
maintenance
• The necessary kit is there
• Difficult bit –
– How are we going to use it?
– Define the processes
– Which variants do we need?

– Under and Over Track Crossings
– Orange Pipes and Yellow Split
Ducting
• Savings of the order 95%
• Reduce risk as the track bed is not
disturbed
• Two variants product accepted
• In use across the whole of Network
Rail as well as Thameslink

Negative Short Device
• The Negative Short Device will be
used to improve the efficiency and
safety of third rail isolations.
• Replace short circuiting straps and
strap-men (can have up to 25)
• Simplifies the process considerably
• Project timescale 40 weeks
• Proposed fit NSDs to London Bridge
low level
• Manual switched solution – not using
SCADA
• Only 25 NSDs needed

NSD Savings
• Reduction in resource needed over 2 years = £840k
• Reduced communication over 2 years, 208 hours = 52 extra shifts
• Not cancelling the first and last trains over 3 years = £300k
• Reduction in risk
– Reduced requirement for line blockages
– Less staff on the infrastructure
– Reduced involvement from interface stakeholders
– No strapping in the wrong area
– Reduced communications
– Reduced staff on track / less chance of injury

Snow displacer
• Very simple, inexpensive
length of foam that sits in
the point ends
• Stops snow (anything
else) from entering and
jamming the points
• Saves delay minutes
• Saves energy (30%) by
insulating the point
heaters

Snow displacer – status
• Thameslink is part of the national programme
• Trial underway at Hither Green
• Further work –
– Develop a version for the very narrow end of the points
– Arrange for points to be automatically fitted to the points at the
factory
– ‘Productionise’ the existing snow displacer for easier fitting

Electro-luminescent PPE
• Worked very closely with the
suppler Fhoss to complete final
development
• Thameslink Route Access Team
is testing 10 sets of PPE
• Battery life 12 hours
• A worker can be seen 1 ½ miles
down the track
• Compliant with Rail Standards
• Additional cost is not significant

Pavegen – electrical energy from foot falls
• Sustainable renewable energy
• Floor tiles form the green area in
the ‘mock up’ photo
• Hopefully drive assets such as
destination boards
• Trial site in the station to be set
up

CCTV Scanning of Pantographs
• A damaged pantograph or shoe can cause
much damage to the infrastructure and very
many delay minutes
• Even more when we are at 24 trains per hour
• CCTV scanning will allow damaged trains to
be sidelined before they enter the
Thameslink central core
• An installation at Farringdon will check that
the pantograph is down as the train travels
south into the third rail area
• Probably the trial site will be at Farringdon

Balise Bars
• Can be used for Balise Bars from
Siemens, Alstrom and others
• Can be fitted or removed in less than
2 minutes using standard tools
• Use standard rail fittings so no drilling
or digging out the ballast
AWS magnets
• Ordinary ferrite magnets –
– Lose strength due to interference
in third rail areas
– Bulky heavy
– Require frequent maintenance or
rebuilding
• Vortok - Rare Earth Magnets
– With an opposing coil and digital
control electronics
– Smaller and Lighter
– Little or no loss of strength
– Plug coupled so quick to fit
Innovation on Thameslink
• Not just be confined to Network Rail
• Surely our partners have innovations as well
• Example – Invensys use the IBM Rational tool provides platform for integrating and
synchronizing product development processes
• The need - Invensys Rail Dimetronic needed to improve its competitiveness and reduce timeto-market for its solutions. This required automating, streamlining and increasing control over
development processes.
• The solution The company used integrated IBM® Rational® software to automate code
generation and speed developers' response to frequent changes and new traffic signal
requirements.
• The benefit The company reduces time-to-market for products by 40 percent and reduces
cost and risks of development by generating all code in compliance with coding standards.
• This case study has been published by IBM
• Please tell me of your innovations on Thameslink
• Are there opportunities for partnering?
