Right on track

Posted: October 24, 2012 in Rail

A fleet of 22 new locomotives – the first of their kind in the world – are set to transform haulage efficiencies for one of Australia’s leading grain businesses, CBH Group.

Cummins’ high horsepower QSK60 and QSK78 engines are the driving force behind the new standard and narrow gauge locomotives, built by MotivePower in the United States.

CBH, a farmer-owned cooperative controlled by nearly 5000 grower-shareholders in Western Australia’s sprawling grain belt, has invested $175 million in its new fleet of 22 locomotives and 574 wagons.

Escalating freight rates and the need to move more tonnes to port more efficiently forced CBH to search globally for a new rail partner.

“We wanted to keep freight rates in check,” says Mike Poore, freight contracts manager for CBH.

“The rates had gone up 38 percent over two seasons while fewer tonnes were being delivered to port.”

Dual-fuel QSK50 will begin production in mid-2013.

Cummins has announced plans to produce dual-fuel engines from 800 hp to 3500 hp for high horsepower markets. The first in the product portfolio, the Tier 2 QSK50 for oil and gas well servicing applications, will begin production mid-year 2013, with other QSK engines to follow.

Cummins high horsepower dual fuel engines will operate with common integrated controls, making a seamless transition from diesel fuel to dual-fuel operation. By default, an engine will run on diesel fuel until the operator selects the option on the control panel to run the engine on a blend of diesel and natural gas fuel. The engine will switch to dual-fuel mode and automatically select the substitution rate for the operator.

Pulling its weight

NZ Steel locomotive has been repowered with a Cummins QSK19.

“She’s a faithful old horse,” quips Te Whitu Anderson, locomotive driver for New Zealand Steel.

The old horse – a Japanese Niigata locomotive – is not so old now, having recently had a heart transplant.

Out came the mechanically-injected Cummins K19 engine which had clocked up more than 25 years of service, and in went an electronic QSK19, pumping out 600 healthy horses.

The QSK19 rated at 600 hp is a Tier 3 emissions compliant engine. Tier 3 levels are the lowest regulated emissions in the world for off-highway engines in this power range.

The Niigata locomotive operates at New Zealand Steel’s fully integrated mill at Glenbrook, 60 km south of Auckland. (New Zealand Steel is owned by BlueScope Steel, formerly BHP Steel.)

The steelmaking operation uses locally sourced ironsand to produce 600,000 tonnes of steel a year. Around 60% of the steel output is exported. (more…)
