Clean Propulsion & Support Technology Committee Meeting

APTA Clean Propulsion & Support Technology Committee

May 2005

To: Clean Propulsion & Support Technology Committee Members
From: Richard Hunt, Vice Chairman for Vehicle/Propulsion Systems
Subject: Technology Project Status Update – May 2005


The following Technology Project Status Updates are submitted for your review and information. As you can see from this small sample, there is a lot going on. It is our plan to update this summary and distribute the updates at each Committee Meeting. If you have any questions or recommendations, please let us know.

WMATA

The Operational Bus fleet is 1441. Of these, 164 are New Flyer 40 ft, low floor CNG buses. We have 250 additional CNG buses on order form Orion. They will be 40 ft. low floor, and are scheduled to be delivered between August 2005 and March 2006. The Orion buses are all replacement buses.

From a technology standpoint, WMATA plans to employ both CNG and Diesel Hybrid. On April 21, 2005 the WMATA Board of Directors authorized 217 additional replacement buses for delivery between 2006 and 2008. 100 of these will be low floor diesel hybrids and 117 will be clean diesel. This allows allocation of these replacement buses to three facilities in Maryland. We are quickly exploring options and hope to have some number of diesel hybrids in service before the end of 2005.

Los Angeles Metro Vehicle Technology Update

Metro continues to be out on the Technology edge. We have received over half of our NABI 45 foot Compo Buses and will take delivery of the first thirty 60 foot CNG Metro Liners in June. The Orange Line Bus way in the San Fernando Valley is scheduled to open later this summer, and will employ the Metro Liner as its base vehicle. With an eye towards 2007 and 2010 vehicle emission requirements, we are looking at a Hydrogen – CNG pilot project, evaluating three different CNG engines, and are working on a Gasoline Artic project.

Disc Brakes

Los Angeles Metro had requested that NABI install disc brakes on a group of buses within the latest order. A review of transit properties indicated that disc brakes were not the braking system of choice in the United States, but the many European transit operators have been using disc brakes for some time with good results.

After an engineering review and analysis, and discussions with Arvin Meritor and NABI, it was agreed to install all axles with disc brakes for both the 45 foot Compo Bus and the new Metro Liner bus orders. From a cost benefit, the mean time to fully reline a conventional brake axle could be as high as eight hours. The time to re-pad a disc brake axle is taking less than one hour. Therefore, the cost savings in labor alone minimized encouraged Metro to take the risk.

To date 69, 45-foot buses have been placed in service with accumulated life miles of 1,069,269. With the exception of one warped front rotor there have been no other defects noted or any warranty claims reported to date. A review of Bus Operators by the Mechanical Training Department indicates nothing but positive feedback. Based on the wear seen to this point, it is conceivable that the first required pad change would not occur until 80,000 miles or more.

In both cases, Meritor tested and certified that the disc brake configuration meets all areas of FMVSS 121 tested the entire braking systems. Certifications are on file.

For information, please contact Richard Hunt (huntr@metro.net) or Mike Bottone (bottonem@metro.net).

Omnitrans, San Bernardino, California

Here at Omnitrans we are still working with our three gasoline hybrid buses. Two are in service and the third is awaiting the upgrade to the latest phase (Siemens system).

Our next bus bid will most likely still be CNG buses as we continue to evaluate our hybrid buses.

Omnitrans is moving towards a BRT system. We are currently performing the MIS study for this project. We like the looks of the latest artics from NABI and will be watching how well they perform at our site.

Massachusetts Bay Transportation Authority Vehicle Technology Update

MBTA in Boston is nearing completion of a complete transformation of its bus fleet to cleaner technology. Since 2003, 460 pre-1994 buses have been retired and replaced with 360 new compressed natural gas and 100 new “emissions-controlled diesel” (ECD) buses. When the remaining 75 ECD buses on order are delivered by summer 2005, 57% of the fleet will have been replaced, reducing the average fleet age from 14 to 4 years.

The ECD buses are equipped with Caterpillar ACERTTM engines certified to 2.4 g/bhp-hr NOx emissions, plus a first-fit diesel particulate filter (DPF) that reduces PM emissions by more than 90%. The engines in the remaining 1994-1995 vintage diesel buses have been overhauled and upgraded to meet 1998 emission standards (4 g/bhp-hr NOx), and have been retrofit with DPFs. In addition, all diesel buses in the fleet now operate on cleaner, ultra-low sulfur diesel (ULSD) fuel, with no more than 30 ppm sulfur.

In late 2004, MBTA also opened the second section of its new Silver Line bus rapid transit service, with delivery of the first “dual mode” articulated buses that will operate through a dedicated transitway tunnel from downtown Boston/South Station, to the South Boston waterfront. From there, the buses will operate over surface streets and to Logan airport. The unique dual-mode buses operate in trolley mode while in the tunnel, pulling their electric power from an overhead catenary system. Once outside the tunnel, a full-sized diesel engine and generator produce on-board electricity to power the electric drive motors. A total of 32dual mode buses are expected to be delivered by summer 2005.

CATA Compressed Natural Gas Program Complete -1993 – 2005

The Centre Area Transportation Authority (CATA), a joint municipal authority of the five Centre Region Municipalities (State College Borough and College, Ferguson, Harris and Patton Townships), is the chief provider of public mass transportation in Centre County, Pennsylvania, providing over six million bus rides a year to Penn State students and staff, commuters, senior citizens and many others.

CATA, having just celebrated its thirtieth anniversary, is very accomplished and respected within the transit industry. It has been given recognition over the years for its strong ridership growth, its responsiveness to the local community, transportation and land use planning, service quality, partnerships with the Pennsylvania State University and local organizations and staff’s involvement in the transit industry. CATA has distinguished itself in many areas, but nothing is more impressive than its full fleet conversion from buses running on diesel fuel to those powered by clean-burning compressed natural gas (CNG).

CATA Compressed Natural Gas Program

In 1993, CATA made a commitment to alternative fuels with a decision to replace its outdated diesel-powered fleet with buses powered by clean compressed natural gas. This action was taken in response to several national priorities: lowering operating costs for essential services, improving air quality through reduced vehicular emissions, and reducing reliance on imported fuels. CATA had an interest, too, in being able to use fuel produced locally in Centre County.

In 1994, as the first step toward fulfilling this commitment, CATA ordered sixteen CNG-powered buses from Bus Industries of America (now Orion Bus Industries) in Oriskany, New York.

In 1995, CATA, the Pennsylvania Department of Environmental Protection and Columbia Gas of Pennsylvania joined in a cooperative effort to build a CNG fueling station at CATA’s administrative facility.

In subsequent years, CATA expanded its fleet three times, bringing the total number of CNG-powered buses to 44. Additionally, a fueling facility and three compressors were constructed on its property, which also provide natural gas to the nearby UniMart.

Today, with the receipt of two new 18-passenger CNG-powered Starcraft buses in January 2005, CATA’s entire fleet is fueled entirely by natural gas. CATA has now been named the first transit authority on the East Coast to have replaced its fleet with one operated entirely by alternative fuel.

“As a pioneer in the use of compressed natural gas buses, CATA has had a very positive experience,” says CATA’s General Manager, Hugh Mose. “Not only have the buses performed well, but the response from the general public has been overwhelmingly favorable. In my 25-plus years of experience in public transportation, I cannot think of an initiative that has created such a positive response in the community as the introduction of CNG-powered buses at CATA.”

Why natural gas?

Growing severity in air pollution problems in many cities, combined with the desire to reduce America’s dependence on imported oil, is causing many transit authorities across the country to reevaluate their current choices of transportation fuels. Natural gas is a transportation fuel that is economical, burns cleaner than diesel and is produced right here in the United States. Not only that, much of the natural gas used in State College is produced locally in Centre County.

While CATA cannot claim that the use of compressed natural gas as a vehicle fuel has resulted in any cost savings, Mr. Mose asserts that “I can say without reservation that CATA’s CNG buses produce only a fraction of the emissions of the diesel buses they’ve replaced.”

CATA/PTI Hydrogen Bus Project

Even beyond its CNG program, CATA continues to partner with local businesses and organizations to explore alternative fuels. In 2004, CATA and Penn State began working with Penn State’s Pennsylvania Transportation Institute (PTI) on a broad research initiative aimed at researching hydrogen as fuel in vehicles and the related benefits. As a result of the project, as many as three of CATA's buses operating on campus will be converted to ones running on a hydrogen and compressed natural gas blend. The groups involved are exploring the emergence of hydrogen as a publicly accepted transportation fuel and evaluating the costs and efficiencies of the fuel as compared to gasoline and other alternative fuels.

CATA CNG Fueling Facility Update Earmark

CATA recently received a CNG earmark, contained in the FY 2004/2005 Appropriations Bill for an upwards of $800,000 to work with Columbia Gas of Pennsylvania and Basic Systems (the engineering firm CATA’s used in the past) to determine and implement the best strategy for rebuilding/updateing its fueling facility housed at its administrative offices. Construction on the project will take place in the Summer of 2006.

King County DOT/Metro Transit Technology Update

Hybrid Buses

King County Metro is operating a total of 236 New Flyer DE60LF artics with the Allison parallel hybrid system (214 are owned by King County, and 22 are owned by Sound Transit and operated by King County under contract). These buses replace the fleet of 236 1990-91 Breda articulated dual power buses that were purchased to operate the routes using the downtown Seattle transit tunnel. The last Breda revenue run on a tunnel route was January 24, 2005. This fleet of hybrids is operating very well, with operating costs down, and miles between chargeable trouble calls up, compared to the Bredas. Small retrofits have been done on the Caterpillar C9 engine and Allison hybrid drive, but overall, this has been a very trouble-free new technology introduction.

Electric Trolley Buses

To replace life-expired 1987 MAN articulated trolley buses, 59 Bredas are being converted into straight trolley buses. Five are completed at present, and project completion is projected for June 2006. The conversion process includes engine, transmission and radiator removal, addition of ABS on the third axle, rebuilding of the driver’s station, removal of some seats to enhance leg room and re-upholstery of the rest, upgrading to LED destination signs, and upgrading to Kiepe current collection equipment. Remaining Bredas are being cannibalized for a supply of spare parts.

The fleet of 100 2002 Gillig/Alstom/Randtronics trolley buses continues in operation, with a couple of retrofits underway to solve problems with electrical corrosion in one of the traction motor bearings and a slight jerk at start-up.

Fuel

ULSD is in use at all bases. Metro has a small grant to demonstrate B5 biodiesel. It is in use at two of seven bus bases. There are no plans to expand the demo or increase the mix ratio given the high price of bio-diesel. It has been operating without issues in Cummins and CAT products.

New Flyer -Clean propulsion update

New Flyer continues to lead in the development and commercialization of hybrid and alternate fuel technologies, with over 2500 natural gas vehicles and over 300 hybrid vehicles in revenue service in North America. In late 2004, New Flyer was awarded Calstart’s prestigious Blue Sky Award for outstanding marketplace contributions to advanced, sustainable transportation. During 2005, 76 gasoline-electric heavy-duty buses will be delivered to six California properties, marking the first order of its kind in North America. This year, the world’s first hydrogen-electric bus, which was built by New Flyer with the hydrogen-hybrid drive system designed and installed by ISE Corporation, was put into service in California after successful cold-weather testing in Winnipeg, MB.
