Railway Applications Colpro's rail traction projects and capabilities are focused on fabrication and supply of: Exhaust systems for diesel traction engines and generators including: - High performance silencers - Expansion bellows - Exhaust ducting - Resilient mounting and supports - Engelhard soot filters and catalytic purifiers - Thermowrap thermal insulation blankets Air inlet silencers Airefil storm louvers Air inlet filtration Air inlet ducting Engine compartment acoustic treatment Colpro Engineering use 3D CAD software and silencer design experience to maximise the available space to fit high performing silencers into unorthodox spaces.

Major Railway Involvements

ABB - Explorer Railcars NSW
Colpro carried out the design, traction and generator diesel exhaust silencers for the complete fleet of railcars.

Goninan - Sprinter Railcars VIC
Colpro carried out the design and construction of the complete diesel exhaust system for the complete fleet of railcars consisting of 44 cars.

BHP Port Kembla - Locomotive Evaluation
Carried out a noise survey on English Electric powered locomotive, to investigate exhaust noise and possible counteractive solutions.

Clyde Engineering - WA Locomotive
Designed and constructed a prototype silencer for Clyde Engineering constructed WA narrow gauge locomotives. Assisted in the noise trouble shooting to bring the locomotives within contract specification, after delivery of full fleet.

Goninan - Prospector and Avonlink Railcars WA
Colpro carried out the design and construction of the complete diesel exhaust and air intake systems for 9 sets of railcars.

Goninan - Locomotive Silencers
Colpro carried out the unique design and structural evaluation of the complete diesel exhaust system to meet low frequency noise levels. The project consists of 9 car sets.
