1. SILENT RAIL FREIGHT IN THE NETHERLANDS Pieter Dronkert Dep of Transport, Rail Freight Divison 25 okt 2005

2. IPG: Dutch Noise Innovation Program Co-operation 2 Departments and Infra Managers Started 2002, Ends 2007 Total budget: € 110 mln. Development and Implementation Cost-Effective Measures Road and Rail

3. IPG-Rail Co-ordinated by ProRail (IM) Budget: € 25 mln Focussed on Track and Rolling Stock Renewed focus: Implementation of Silent Rolling Stock

4. IPG-Rail: Successes - Fixed Noise Measure Spots - Tuned Raildamper - Acoustic Grinding - Retrofit Project(s)

5. Tuned Raildamper

6. IPG-Retrofit: Composite Brake Blocks Cast Iron Blocks: Rugged Wheels cause more Noise Whispering Train: K-block project LL-blocks: pilot project(s)

7. Whispering Train Project: K-Blocks Target: More Information about Retrofitting with K-blocks and Noise Reduction of 7-10 dB – Acoustic Measures and Effects – Life Cycle Cost – Retrofit costs

9. First Results Whispering Train Project - Noise reduction: 9 dB for K-Blocks and Wheel Dampers togehter - Another 1 dB for TKS-spring - Costs Retrofit: € 6.000,- for K-blocks - LCC: frequent replacement needed due to asymmetric wear

10. LL-pilot(s) IPG: looking for 2 pilots Testing all 3 released LL-blocks Start: beginning 2006 Halfway 2007: results Target pilots: more information and permanent release LL-blocks

11. Retrofitting Freight Wagons With K-blocks: – expensive With LL-blocks: – hopeful development – need permanent release – do pilots etc

12. Implementation Silent Freight Wagons Possibilities: –EU- or National Financial Support Retrofitting –Discount on Track Access Charge –Noise Production Limits

13. Discount on Track Access Charge EU 2001/14: discount TAC possible Discount TAC incentive for Operators to Retrofit Dependent on availability and success LL-blocks
