Public Conference December

2. Rail Specific Planning and Development Analysis, Phase 2
Subject 1 – Further review of single track high speed railway lines
Acceptance criteria of punctuality
Design of crossing loops
Subject 2 – Track connections on high speed railway lines
Design of passing loops
Design of track loops
Subject 3 – Station on High speed railway lines
Station design
Effects of high speed rail stop
Benefits of station establishment
Experiences from other countries

3. Acceptance Criteria for Punctuality
Interim Report are delivered
Punctuality is an important factor in railway operations. It is a central measure of performance and it is widely used to evaluate effectiveness of infrastructure investments and timetable adjustments.
Conclusion and proposal in the interim report:
“High speed lines shall be constructed for punctuality on five minute level within the interval %. Assuming negative exponential distributed delays these values corresponds to mean delays of 1-3 minutes.”

4. Design of Crossing loops
Single track
Length of
crossing loops?
Train A
Train B
Crossing loops
Length between
crossing loops?

5. Design of Passing and Track loops
Double track
Length between
passing loops?
Length of
passing loops?
Freight Train
High speed Train
Passing loops
High speed Train
Track
loops
Length between
track loops?
Track loops – Flexibility and Maintenance
Alternative design
for passing loops

6. Station Design
How to design stations on single and double track high speed railways?
Important issues are for example flexibility for the train traffic and safety
arrangement for passengers.
Example design for station with only IC- stop and high speed train passes
IC - Train
High speed Train
Needs of safety arrangement such as
screens, fences etc at platforms or between
tracks when high speed train passes
IC - Train
High speed Train

7. Effects of high speed rail stop and Benefits of station establishment
How many intermediate station for high speed rail stop can there be ? ? ? ?
Existing railway and station
Where to locate a station ?
City
New High speed line and station

8. Some general facts ! A High speed train at 300 km/h:
Needs a distance of 18 km to reach the maximum speed of 300 km/h
Needs a distance of 4,5 km to stop from the maximum speed of 300 km/h
The addition time for an extra station stop is approx. 4,0 – 5,0 minutes
A High speed train at 250 km/h:
Needs a distance of 8,5 km to reach the maximum speed of 250 km/h
Needs a distance of 3,0 km to stop from the maximum speed of 250 km/h
The addition time for an extra station stop is approx. 3,5 – 4,5 minutes

9. Station Design – Experiences from other countries
Determination of considerations for station provision
Produce questionnaire to several railway authorities
Analysis of responses to questionnaire
Desk top study of international experience
Production of summary infrastructure and operational costs
