7. New high speed record
On 14th September 2008 on the Main Line track Skövde – Töreboda
the Regina 250/300 reached the new high speed record of 303 km/h
© Bombardier Inc. or its subsidiaries. All rights reserved.
This was done on track certified for 200 km/h operational speed
Direct after the test was finished the line went back to normal
operation

9. Track-friendly soft bogie for Regina 250/300
Based on 25 years of experience with track friendly soft bogies
Meets UIC518 requirements for 250 km/h
and cant def 183 mm (1.2 m/s2). Track forces is typical 60 % of limits.
Has been running 303 km/h (new record in Sweden)

10. Active Lateral Suspension (ALS)
Two functions in one hard ware
1) Keep carbody in centred position in curves
→ Wider carbody possible
→ Better cross wind stability
© Bombardier Inc. or its subsidiaries. All rights reserved.
⇒ Improved lateral ride comfort by avoiding bump stop contact
⇒ Possible to run at high speeds in curves
2) Improve lateral ride comfort
⇒ Same ride comfort at 250 km/h as without
active lateral suspension at 200 km/h
+25%
Wider carbody
3,6 m in Gröna Tåget, if required

12. Permanent Magnet Motor Drive
Summary
PM motor offers environmental and economical advantages
– which in future has the potential to increase in relevance
– reduced energy consumption
– higher efficiency and power
© Bombardier Inc. or its subsidiaries. All rights reserved.
– simplified cooling
The MITRAC PM motor design is based on industry standard
Successful tests confirmed the advantages of MITRAC PM motor
and the expected benefits
