REALISATION

Apologise or Anticipate?

Sorry

Anticipation is the Driver

The more automated a rail system,

the higher the customer‘s need

for individual attention in case of disruptions

Anticipate, adapt and communicate

SERVICE INTENTIONS9

Managing Service Intentions is the Vision

VISION

Service Intention Examples:

• Transport Service within a time frame

• Transfer Connection to another transport service

• Service Quality, such as ...

• bicycle wagon

• guided children wagon

BLUEPRINT (2)

Reduced computational complexity

Using formalized service intentions allows massive

Reduction of computational complexity

Basic concept:

• Separation in two levels: Macroscopic and microscopic level

• Relaxing the problem definition by using service intentions opens

the solution space and reduces complexity

• Focus on solving local problems in hot spots (stations with high

utilisation) and then fill in the blanks in-between

Formalized in

«Algorithmic decision support for train scheduling in a large and highly

utilized railway network» PhD Thesis from Gabrio Curzio Caimi

Allows to reschedule at the whole Danish railway network at least every 6 seconds

Signalling Programme

Background

– Punctuality decreasing while

maintenance costs increasing

– 50% of today's train delays

are due to signalling failures

– Systems from 1930 still in use

17

Processes and ways of

working are unsuitable

The Unique Chance

1 Total replacement of the Signalling System

in one Project

2 Transform Traffic Management

Total Replacement of the

Signalling System

in one Project

– A Euro 3.2 billion replacement

programme of renewing all Danish

railway signalling together between

2009 and 2022

– Moving from track side signalling

to in-cab signalling

Changing Culture

as premise for Benefit Realisation:

From Production to Service Culture

We chose to include Culture

A railway the delivers

high quality services to

well informed passengers

even during disruptions
