R.2. Design of the railway layout considering energy
consumption aspects
Investment: Nature: Improvement:
An efficient layout design in terms of energy consumption is understood as a
homogeneous speed profile.
The homogeneity of the speed profile reduces the use of the brake to decelerate on the
line, limiting it to stops. In many cases, it implies that speed is less than the maximum
possible speed and can lead to a significant reduction in the average speed of the trip.
To achieve this homogeneous speed profile with a minimum reduction in average speed,
it is recommended:
To avoid specific speed limits.
Gradient at stations is elevated, to minimise the necessary braking on approach.
Gradient at stations is horizontal to reduce starting power.
Slopes are harmonised with the speed allowed by the sections.
