Balfour Beatty (Edgar Allen) - Switches and Crossings (Frogs) for Main Line Railway, Light Rail, Tramway, Docks and Harbours

Edgar Allen specialises in the design, manufacture and supply of switches and crossings (S&C) for railway / railroad systems. Our products include complete junction schemes, turnouts, crossovers, double slips, and individual units such as asymmetric switches, weldable manganese steel crossings (frogs), swing nose crossings, diamond crossings, expansion joints and insulated joints.

The company's design capability is substantial, and Edgar Allen's fully approved RT60 system (UIC60 rail) has been adopted by Network Rail for the UK route network.

In terms of austenitic manganese steel (AMS) special trackwork design and manufacture, Edgar Allen is a world leader, and is a regular exporter particularly to the USA (AREMA - 982, 988, 989, etc.) and Hong Kong (MTRCL, KCRC, HK Tramways). All our cast manganese steel units are cast in our own foundry in Bathgate, Scotland.

MAINLINE RAILWAYS - TURNOUT ENGINEERING

Edgar Allen has always been one of the UK rail network's premier turnout suppliers, and we are proud to be continuing this long association with the adoption of our RT60 system by Network Rail. However, the company also supplies overseas networks (including USA, France, Ireland, Australia, New Zealand and Hong Kong).

Edgar Allen's designers have unparalleled global railway experience. Our customers include national networks (passenger and freight), high-speed commuter networks and heavy haul railways. Our turnouts are designed to UIC, AREMA or customer specific requirements, to suit any rail section.

SWITCHES, CROSSINGS AND RAIL FOR TRAMWAY AND LIGHT RAIL SYSTEMS

Paved (street-running) systems require special designs and materials, particularly where longevity is required to avoid periodic road excavation and/or road closure for maintenance and repair.

Edgar Allen's flexible manganese steel switches (points) are proven in the UK and around the world, and feature smooth operation, longevity and low maintenance. Points may be supplied suitable for power-, hand- or vehicle operation, with or without spring return.

Edgar Allen frogs and crossings may be supplied with deep or floored grooves (for flange running) to suit any rail section.

We also manufacture cast manganese steel rail for tight curves and tram loops; this product normally lasts around six times longer than standard rail in these applications.

SWITCHES AND CROSSINGS FOR MASS TRANSIT AND UNDERGROUND / METRO SYSTEMS

Edgar Allen supplies some of the world's premier mass transit and underground networks. In Hong Kong, we have been an approved supplier of switches and crossings to MTRC Limited for 25 years, and we proudly manufactured and supplied all of the switches and crossings for the Tseung Kwan O Extension (TKE), including UIC60 turnouts, diamonds, double slips, and depot scissors and turnouts.

In the UK, we have been a long-standing supplier to the LUL network, and supplied all the crossings for the Jubilee Line Extension.

DOCKS AND HARBOURS

Quayside Systems present special challenges, especially where railway / railroad and crane tracks intersect. Edgar Allen has the experience and expertise to design and manufacture solutions for complete quayside (navy and port authority) schemes.
