Thompson East Cost Line, Singapore

Tuned at 510Hz, vertical and lateral direction
280m damper section
300m track curvature, S-curve
High attenuation baseplate
3 / 1 damper per sleep bay at low rail
1/2 damper per rail support spacing at high rail
80% Rail Corrugation Growth Suppression

Corrugation were measured by Corrugation Analysis Trolley at 1 – 6 months after grinding. Corrugation growth rate is compared between damper and control section at the same curve with the same curvature. 80% corrugation growth rate reduction is achieved. Detail measurement data will be published once the project is finailised.
