P. 2/ Railway infrastructure: a sound market with huge opportunities
P. 2-4/ Alstom portfolio of infrastructure solutions becomes broader
P. 5/ Crossrail, a showcase of Alstom infrastructure solutions
Alstom has developed strong know-how for the design,
supply, construction, tests and commissioning of railway
The infrastructure market represents around 20%1
of the railway market, of which around
70% is accessible. The accessible market for infrastructure remains smaller than for rolling
stock and signalling, as some countries apply more protectionism and a lot of the
maintenance is performed by the operators only. The infrastructure accessible market is
growing at a steady rate of 3.3% per year is expected to increase by 2019 due to the
opening of some countries. Alstom has a complete range of solutions and proposes a large
portfolio for infrastructure.
All data of this section are taken from UNIFE report (September 2014)
Railway infrastructure: a sound market with huge opportunities
The market is divided into two main domains: electrification and superstructure, i.e. track.
The electrification part represents 20% of it. Between 2017 and 2019, the electrification
market should grow by 4.5% a year thanks to programmes across Europe (UK and Poland),
Russia (Moscow ring and very high speed lines construction) and USA (urban projects). The
track market will grow at an annual rate of 3%.
75% of all infrastructure works are performed on mainlines and freight lines. This market is
growing by 3% every year. With the perspective of new very high speed lines (UK, Sweden,
USA…), UNIFE is forecasting an 8.6% growth in electrification, and 4% in track. As the
tramway market is booming, tram electrification is increasing by 7.2% yearly.
Europe remains the largest market for infrastructure and is expected to increase by 3.4%
per year, driven by national programmes, especially in the UK and the Nordics. The
emerging regions are undergoing a high yearly growth, especially in Latin America (+ 10%),
Middle East and Africa (+4.9%) and CIS (+ 9.7%). USA and India will be the main markets in
the coming years.
Infrastructure accessible market by region between 2017 and 2019 (25 billion euros)
The infrastructure market is also supported by the rise of turnkey projects. The share of
these projects (15% today) in the infrastructure business will double in the next three years,
notably thanks to projects in emerging areas.
Alstom portfolio of infrastructure solutions becomes broader
Alstom portfolio of infrastructure solutions has been expanded over the last few years and
can be proposed as separate lots or in the frame of turnkey systems. Alstom is able to offer
electrification solutions (feeding systems and power supply systems), track (concrete slab
track) and infrastructure equipment (depot equipment, tunnel ventilation, escalators,
ticketing, platform screen doors…) – either for new lines, extensions and refurbishments or
maintenance, and both for urban and mainline projects.
Alongside its expertise in the execution of track, electrification and electromechanical
equipment projects, Alstom develops innovative infrastructure solutions to achieve reduced
costs, faster delivery or improved energy efficiency of urban transport projects.
APS, Alstom’s ground-level power
supply solution, is one of its flagship
solutions for tramways. With this
catenary-free solution, the power is
supplied to the tram through a
segmented street-level power rail. The
conductive segments are switched on
only when the tram fully covers them,
ensuring total safety for pedestrians
and all road users. The power is picked
up by contact shoes located under the
vehicle, on the tram’s central bogie.
APS helps preserve the beauty of the
urban environment while guaranteeing
the same performance as overhead contact lines. Last year, Alstom delivered and
commissioned the world’s first 100% catenary-free line with Dubai tramway. Lately, Alstom
has introduced to the market another electrification solution: SRS, an innovative ground-
based static charging system for trams and electric buses equipped with onboard energy
storage. This solution is derived from APS, with the same functional and safety principles. It
is designed to recharge electric vehicles’ supercapacitors or batteries in less than 20
seconds at passenger stops or
within a few minutes at the end of a
bus line. The vehicle positions itself
over in-street power rails (tram) or
pads (bus) and the current is picked
up by a contact shoe located under
the vehicle. In November 2015, the
tramway of Nice, France, ordered
SRS for its new Lines 2 and 3.
Alstom also offers design, development and manufacturing of electrification components
(third rail, catenary cantilevers, rigid catenary, steady arms, tensioning and anchoring
systems, etc.) Its three major solutions in this field are CLever, a new main-line cantilever
with reduced parts for easy installation and maintenance, offering high adjustability with a
wide range of possible configurations, the Rigid overhead catenary, and the Third Rail
which has a long lifespan (30 years) and is adaptable to customer needs (voltage, current)
and to any civil works / rolling stock constraints.
As track works play a significant role in the duration of a project, Alstom designed
Appitrack, an automated track-laying solution allowing the installation of urban tracks up
to 4 times faster than with traditional methods, leading to a reduction of disturbances,
costs and CO2 emissions, while increasing safety and cleanliness on the worksite.

Alstom co-developed NBT for main-line owners seeking a concrete track, i.e. a railway
track with extensive lifespan and high infrastructure availability, which can be installed
faster than traditional slab track, and be operated for mixed traffic (both passenger-
dedicated and freight transport). The installation of NBT is compatible with the the service-
proven Appitrack track-laying technology, which allows unmatched construction rates. The
main advantages of slab tracks include: long life-span (100 years), reduced maintenance,
high infrastructure availability and increased operating revenues. It is suitable to all speeds
and climatic conditions (no flying ballast, no sand contamination, etc.), it offers optimised
track alignment (tighter curves and higher cants) and reduced civil work footprint.
Alstom also co-developed HAS, a track solution,
particularly suitable for metros, composed of
concrete sleepers on resilient pads placed in a
rigid boot, attenuating ground-borne noise and
vibrations. Quicker to build and easier to
maintain, HAS offers the same performance as
floating slab track systems, at a lower cost.
To deliver better energy efficiency for urban and suburban
rail transport networks, Alstom created Hesop, an
advanced power-supply substation. It reduces energy
consumption by recovering over 99% of the available
energy generated by trains in braking mode, and by re-
injecting it into the network to feed station equipment or
back into the grid. Hesop also optimises the power
required for traction permitting reduced infrastructure
investment. Hesop is in operation on the Victoria Line of
the London Underground, United Kingdom.

Crossrail, a showcase of Alstom Infrastructure solutions
The ATC joint venture, consisting of Alstom, TSO and Costain, has been awarded a contract
to fit out and commission the Crossrail tunnels currently being bored under the streets of
London. It sees the Alstom-led joint venture fitting out the 21 km of twin tunnels that will
stretch under London with the track and power equipment necessary for Crossrail trains to
operate from 2018.
ATC is installing over 40km of track, together with rigid overhead conductors, a system that
is being used for the first time in the UK to power heavy mainline trains through tunnels.
The Crossrail tunnel fit-out works also require over 50,000 cubic metres of concrete
delivered by a unique ‘concrete train’, as well as the installation of 48 ventilation fans,
40km of walkways, 66 drainage pumps, 40km of fire mains, and lighting throughout the
The fit-out works are being carried out within the entire tunnelled section of the Crossrail
route between Royal Oak, Pudding Mill Lane and Plumstead Portals.
Two main innovations are being supplied by Alstom: HAS, which is under implementation
on the Crossrail project, with more than 5,000 sleepers being installed in sensitive sections
of the line and the Rigid overhead catenary, compact and easy-to-install and maintain.
