What is information?

Models are spaces for meaningful things

How to Qualify Asset Condition?

To qualify = To restrict
The simple Way,

 427 km Track (total)
(345 km operational length)
 1.128 Turnouts
 (568 in operational length)
Now lets start!

Creation of a valid database for:
1. the sustainable multi-year planning of the necessary track
renewals
2. the creation of strategic forecast models
3. the development of Life-Cycle-Cost models
→ Project „Transparent Track“ (beg. 2014, ongoing)

This is what Data Management is all
about -
in the beginning!

Addition of parts relevant to vehicle dynamics (breaking track)
Track doesnt decay without vehicle operation!
Furher Information: Dynamics!

The not so simple Way, REMEMBER?

Remember what Information is!

Rail Grinding
2014, 2015
Noise and vibration
Complaints
Broken rails
2015
And even more Data to be considered!
ultrasonic measurements

Good Practice Decision Methods

Color code evaluation from track gauge data
rail wear values
Blue: RT >35 / RB <40
Green: RT >31 / RB <45
Yellow: RT >28 / RB <60
Orange: RT >24 / RB <60
Red: RT ≤24 / RB ≥60
Make the difference!

Link Information to Service Quality

(Lines 6, 18, 49, 60; 2018)

Starting Point: Raw Data…But: What is raw?

And then: Trends!
Its all about mathematics

Big Picture of estimation

Lets be serious! The Art of Visualisation
only what one can understand, can become reality
