Rail Fastenings Systems

DRS Baseplate

The DRS baseplate is a double-resilience e-clip fastening system that is ideal for use on non-ballasted tracks when ground-borne noise and vibration reduction are required.

DRS Baseplate product overview

Originally introduced in the 1980s, today’s evolution of the DRS baseplate is the trusted solution for metro, light rail and mainline slab tracks worldwide.

  • Widely used on bridges, viaducts and in tunnels, it is suitable for all rail inclinations and rail types.
  • The DRS baseplate is mounted on a studded, natural rubber pad that can be tuned for different axle loads and stiffness requirements.
  • With a threadless fastening system and parts that can be replaced in situ, the baseplate requires minimal maintenance.
  • Formerly known as VIPA DRS.

Advantages of using Pandrol DRS Baseplate

01

Versatile

The DRS baseplate is adjustable, can be installed in different ways and is available in a range of configurations, making it a versatile option for all non-ballasted tracks and rail types.

02

New or Renew

Its versatility also means that it is the ideal solution for new-build tracks, renews and retrofit applications.

03

Less Vibration

The resilience provided by the baseplate’s rubber pad mitigates the effects of ground-borne vibration and secondary noise.

04

Insulated

High levels of electrical insulation increase the product’s efficiency and cost-effectiveness.

05

Compact

The compact footprint provided by the 2-hole baseplate reduces the size of pre-cast concrete elements required.

Technical features of the Pandrol Fastclip

01

Variable baseplate options

The DRS system is available with different baseplate configurations: a 2-hole offset footprint and a 4-hole inline.

02

Compact footprint

The 2-hole DRS baseplate provides a very compact footprint.

03

Electrical insulation

The baseplate system provides an exceptionally high level of electrical insulation, with the rail insulated from the baseplate and the baseplate insulated from the concrete slab.

04

Adjustability

The DRS baseplate achieves typical lateral adjustment of +/-5mm, with additional adjustability possible to meet specific requirements. Typical vertical adjustment of up to 12mm can be achieved with shims.

05

Track structure interaction

Rail fastening clips for the DRS baseplate are available in low toe load and a zero longitudinal restraint (ZLR) configuration to deal with the effects of track structure interaction.
