TRACKWORK SYSTEMS

SWITCHES

Products can be manufactured against approved drawings and coordinated with the adjoining rails, sleepers, fastenings and operating arrangements of the complete turnout.

TRACKWORK SYSTEMS

SWITCHES ENGINEERED FOR CONTROLLED ROUTE MOVEMENT

CAL Group develops turnout systems around the geometry, loading, operating movements and interfaces of the complete track layout. Design and manufacturing capabilities extend from individual components to coordinated turnout assemblies.

SWITCH RANGE

DEVELOPED AROUND MOVEMENT, FIT AND TRACK GEOMETRY

OVER-RIDING CURVED SWITCHES

Over-Riding Curved Switches use curved switch rails configured to support the required route movement and turnout geometry. Controlled machining and fabrication help maintain the required rail profile, fit and alignment across the complete switch assembly.

THICK WEB SWITCHES

Thick Web Switches provide a robust switch-rail configuration for demanding railway applications. The switch geometry, machining, interfaces and operating requirements are coordinated with the applicable turnout design.

LONG-COMPONENT CAPABILITY

ACCURACY MAINTAINED ACROSS THE COMPLETE SWITCH LENGTH

Turnout design begins with an understanding of how the route will be used, what loads it will carry and how it must fit within the available railway layout.

LONG-BED MACHINING

CNC equipment with X-axis capacities from 3 to 13 metres supports controlled machining of long railway components.

MULTI-AXIS MACHINING

Three-axis, five-axis and double-head capabilities help reduce repositioning while maintaining control over critical profiles and interfaces.

RAIL PROFILE DEVELOPMENT

Switch-rail profiles and transitions are machined around the applicable drawing and functional requirements.

CONTROLLED FABRICATION

Fabricated elements are produced and checked against defined geometry, alignment and interface requirements.

DIMENSIONAL INSPECTION

Profiles, straightness, alignment, interfaces and other critical dimensions are verified using controlled measurement methods.

COMPLETE INTERFACE CONTROL

THE SWITCH MUST WORK WITH THE TURNOUT AROUND IT

STOCK-RAIL INTERFACE
The relationship between the switch rail and stock rail is controlled to support fit, movement and wheel guidance.
OPERATING INTERFACE
Switch movement and operating connections are considered within the requirements of the complete arrangement.
SLEEPER AND FASTENING LOCATIONS
Mounting positions are coordinated with the sleeper layout and applicable fastening system.
ADJOINING TRACKWORK
Closure rails, crossings and other turnout components are considered as connected parts of the final route.

CONTROL BEGINS WITH THE CORRECT SWITCH GEOMETRY.
