Sleeper pads for efficient vibration protection
The track of the London Underground District Line was completely renovated between Paddington and High Street Kensington stations in the city centre. Around 208 million passengers use this line every year.
Between July and August 2011, this very busy section of track, which is also part of the Circle Line, was upgraded with new ballast, rails and brand new sleepers with pads supplied by Getzner.
- Track renovation for London Underground
- Very busy railway line
- Vibrations caused by the underground trains (residential areas)
- Tight track
- Minimal sleeper spacing increases sound transmission
The Getzner solution
Providing elastic bearings for this stretch of the District Line was the first sleeper pad project for London Underground: the requirements called for the use of full-surface Sylodyn® sleeper pads. Deliveries were made both to the CEMEX sleeper works and directly to the operator.
«The lateral bearings enabled us to drastically reduce the transmission of sound and vibrations through the tunnel wall. This also enhanced the vibration-isolating effect. Both the functionality and the price/performance ratio of the proposed solution greatly impressed the customer», observed Stefan Potocan, head of Product Management at Getzner.
Advantages for the customer
- Reduction in sound transmission through tunnel walls
- Elastic pads on bottoms and outsides of sleepers
- Significant cost benefits through efficient preparatory work in sleeper works
- The decrease in vibrations noticeably improves the quality of life
„We have already worked together with Getzner on a number of projects – both for Network Rail and for London Underground. Getzner supported us with excellent customer service and was also present on-site during installation, when required. We look forward to continuing our working relationship in future projects – to the ultimate benefit of our customers.“Andrew Carey, Sales Manager of the sleeper manufacturer CEMEX Rail Products
