Management of Locomotive Exhaust Emissions

The Australasian Railway Association publishes data provided to it by freight rail operators to meet the operators’ obligations under the Code of Practice for Management of Locomotive Exhaust Emissions.  The Code focuses on two key priorities; greenhouse gases and diesel particulates. 

Diesel engines create several emissions of concern to the community, including diesel particulates (PM), oxides of nitrogen (NOx), and greenhouse gases (GHG).

Diesel engines are one of a number of sources of these emissions, and the exhaust from diesel locomotives used in the haulage of freight on rail comprises only a small part of total emissions. The Industry has already taken action to reduce fuel usage, however the rail freight haulage industry has decided as part of its general environmental improvement programs, to take additional action on this issue.

The Code of Practice Management of Locomotive Exhaust Emissions which came into effect on 1 December 2018, seeks to address these Australian environmental concerns through a balanced approach to these competing emission outcomes. In the Australian context, PM and GHG emissions are considered higher priority issues than NOx emissions. As such this Code has reflected the broader priorities in addressing locomotive emissions.

In summary the Code:

  1. Sets a maximum particulate emission standard for new locomotives..
  2. Requires that locomotives receiving a major overhaul (variously called a component change out or power assembly change out) will, where its current emissions of particulate matter are greater than 0,3gr/KWh, be fitted with an upgrade kit comprising enhanced pistons, injectors and other parts, and certified to bring emissions to or below that level.

 

Please refer to the Code here for full details.

 

Companies are required to report annually on their implementation of the Code, as shown in the Tables below.

Operator Notes

Fortescue: All locomotives in the Fortescue locomotive fleet are compliant with the RISSB CoP for management of locomotive exhaust emissions, having PM emission levels below the 0.27 g/kWh level.

GWA: GWA are planning to overhaul a number of non-compliant locomotives in 2019. GWA are planning to upgrade these in accordance with the relevant RISSB code.

Pacific National Prior certification lapsed on overhaul. Awaiting documents confirming certification or to undertake testing

Roy Hill:  All locomotives supplied as and believed compliant. Awaiting documentation to confirm compliance.

SCT Logistics The 8 non-compliant locomotives represent SCT’s shunting fleet that do low kms. and are operating in SCT depots around Australia. SCT’s high km line haul fleet, comprising 15 SCT & 12 CSR Class Locomotives meet the emission standards set down in the Code.

 

 

Explanatory Notes

1. Best Available. Where locomotives need to meet special network requirements a model meeting the Code may not be available. In that case the operator must purchase the type closest to the emission requirement.

2. Major Overhaul is a scheduled power assembly change out, component change out or other planned maintenance requiring replacement of 75% or more of the pistons and cylinder liners of the engine.

3. No Upgrade kit. Kits of enhanced components are not available, mainly for some older locomotives such as Alco models.

4 Disposals: Includes scrapping, sale (net of any purchases of old locomotives), and transfers to non-commercial entities such as heritage museums
