Amtrak Conducts 1st Midwest Charger Test

April 20, 2017

One of the new SC-44 Charger locomotives that will be assigned to Midwest Corridor trains was tested between Chicago and Milwaukee on Wednesday.

No. 4611 was on the point for test train 941 from Chicago to Milwaukee, running ahead of the regularly scheduled Hiawatha Service No. 329.

It was the first test of a Charger locomotive in the Midwest. Testing has been conducted previously on the east and west coasts.

Two Chargers, Nos. 4611 and 4604 arrived in Chicago late last month.

Siemens built the Chargers at a factory in California as part of an order placed by the departments of transportation of Illinois, California, Michigan, Missouri, Washington and Maryland. The order was for 69 locomotives of which Illinois purchased 33.

Most of the Chargers in the Midwest are expected to operate on corridor routes radiating from Chicago.

Further tests of the Chargers are expected to be performed on other Midwest routes.

Cummins Delivers Diesel to be Used in Passengers Locomotives Being Built by Siemens in California

October 3, 2015

A diesel locomotive to be used in locomotives being built for Midwest, California, Florida and Washington state passenger service has been shipped to the factory assembling the locomotives.

Cummns Inc. said the first production 95-liter, 16-cylinder QSK95 engine built to a rail specification has been received at the Siemens plant in Sacramento, California, that is assembling the Charger locomotives.

The engine is rated at 4,400 hp (3,281 kW). Siemens is building the locomotives as part of a 35-unit order placed by the departments of transportation of Illinois, California, Michigan, Missouri and Washington.

The Charger locomotives will also power the trainsets for All Aboard Florida.

Cummins said that the QSK95 can support a top locomotive speed of 125 mph, which achieves the highest output of any 16-cylinder high-speed diesel

The company said that the combination of its Modular Common Rail Fuel System with quad-turbocharging allows the engine to deliver reduced noise and good response in a smaller footprint than medium-speed diesels traditionally used in locomotives.

The engine is compliant with U.S. Environmental Protection Agency Tier 4 emission standards.

Siemens Favored for Locomotive Contract

An Illinois Department of Transportation official is recommending that Siemens be awarded the contract to build 32 to 35 diesel locomotives for use on Amtrak routes in the Midwest, California and Washington state.

The recommendation was made by William Grunloh, Chief Procurement Officer for IDOT, which is the lead agency for the  joint procurement of the locomotives.  Also participating are state departments of transportation for California, Michigan, Missouri and Washington.

The distribution of the locomotives is expected to be 21 units for Midwest corridor service, six to California and eight to Washington.

The number of locomotives acquired hinges on the availability of funding. The states hold options for up to 225 additional locomotives.

Funding the initial purchase will be the Federal Railroad Administration and California Proposition 1B bonds.

Providing final offers were Electro-Motive Diesel, Siemens and MotivePower. IDOT found that Siemens had the highest combined “responsiveness” and price scores.
The locomotives will meet the Next Generation Equipment Committee’s PRIIA 305-005 Locomotive Specification, which was released in July 2012.

The units will be EPA Tier 4 compliant and feature AC traction with a streamlined car body. They will have electronically controlled air brakes and blended air/dynamic braking and will be capable of MU and push-pull operation.

The specification calls for sufficient power for two units to move eight bi-level coaches at 125 mph with a minimum of 600kW of head end power for heating and cooling the coaches. The trucks may be of four- or six-wheel design.
EMD’s proposed 4,700 horsepower F125 was to be powered by a Caterpillar C175-20 engine.

MotivePower’s proposal has not been disclosed, but it is thought that it would have been based on the HSP46, a 4,600 horsepower locomotive being built for the Massachusetts Bay Transportation Authority. The HSP46 uses a Tier 3 General Electric GEVO-12 engine and GE AC  electrical equipment.

Siemens and engine builder Cummins have announced a partnership. The units are expected to use a Cummins QSK95 engine rated at more than 4,000 horsepower.
