Transport energy and emissions
¾ The Spanish Railway Foundation,
as well as supporting and coordinating research in
the industry,
has four specialized Study and research groups,
providing leadership and able to offer made to
measure solutions and integrate actors in the
industry.
¾ One such group is the Transport energy and
emissions group,
specializing in transport, especially the railway, and
with particular relevance in high-speed.

¾ One of the working areas of the Group is the
participation and leadership of large research
projects.
¾ Two projects can be highlighted from those
carried out to date,
promoted and headed by the Spanish Railway
Foundation,
and funded by the Ministry of Public Works
through the CEDEX:
¾ EnerTrans (2006-2009)
¾ ElecRail (2007-2010)

EnerTrans
¾ The aim of the Enertrans project was to
determine and compare the consumption
functions of the different modes in a
homogeneous and solid way.
¾ Common elements were sought in consumption
functions of the different modes, and differential
factors.
¾ The following were considered to make
homogeneous comparisons: route differences ,
consumption in the construction of vehicles and
infrastructure and homogenization of vehicle
capacity.

¾ The aim of the ElecRail project was to study the
characterization of electricity consumption by trains and
identify areas for improvement.
¾ An energy flow diagram was established for the Spanish railway.
ALPI
Energy evaluation¾ The characteristics of the railway electricity network were

defined and modelled for their best design.
¾ Actual consumption measurements were taken on trains and
substations, which were integrated into energy recovery and
storage models, both on board and on the ground,

• Analysis of the interaction between them.
Interconnection
¾ Efficient train operation models were developed in commuter
and high speed trains.
• For the first time these models take into account the different level

Models and studies
¾ In addition to participating in research projects,
the group conducts research and develops
models to support different work.
¾ Main features:
• The ALPI model
• The work entitled "Methodology for
assessing the energy efficiency of railway
rolling stock”
• Tool for planning railway freight trafficPlanCargoRail

of railway rolling stock was commissioned to the
Foundation by IDAE (Ministry of Industry)
(commuter and high speed trains), Metro de Madrid,
Barcelona Tramways and the Railways of the
Generalitat of Catalonia
¾ The ultimate aim was to assist the design of energy
efficient trains, allowing an evaluation of consumption
prior to construction.
¾ The project is compatible with Rail Energy, since it
assumes the same input assumptions and also
provides a specific calculation method that does not
exist in Rail Energy.

Tool for planning railway freight
traffic
¾ Knowing the freight transported, infrastructure
conditions and traction restrictions, the tool makes it
possible to determine the number of trains required,
their characteristics, economic performance and
energy consumption.

Studies for the UIC – High
speed
¾ The group has carried out and continues to carry out
studies for the UIC High Speed Group in various
areas (costs, energy, operation).
¾ This featured the study carried out in 2010 on the
relationship between train speed and energy
consumption.
¾ A study is being carried out into the reduction of
energy consumption by increasing speed on
downhill gradients.

Next steps
¾ The study group continues to work on both its
own studies and projects and in collaboration
with other bodies and specific consultancy.
¾ It is currently working on the modelling of
energy consumption and emissions for a study
of the social and economic profitability of
infrastructure.
ƒ As an addition to the project it is looking for partners to
systematically undertake an estimate and analysis of
energy consumption in transport infrastructure and its
distribution in life cycles.

¾ The project to be tackled concerns the interconnection of
railway networks (high speed, conventional trains,
undergrounds, tramways, station networks, etc ...)
with the general public network, with storage devices at
substations and on board and storage mass management
of vehicle batteries in station parking points.
¾ It develops models to enable proactive management of
energy imported and exported by trains, deciding when to
send to the station, to store, return to the public and even
when to import for storage and subsequent return.
¾ The analysis will be performed in both energy and power,
separating rail consumption (never interruptible, interruptible
in cases of great necessity or easily interruptible) and even
looking at the possibility of providing the system with kinetic
energy from trains.
