Dear Elizabeth, Dear Air Resources Board, Thank you for the opportunity to comment on this draft version of the Technology Assessment: Freight Locomotives (April 2016) [http://www.arb.ca.gov/msprog/tech/techreport/freight_locomotives_tech_report.pdf]. We hope that our comments will be valuable for the development and completion of this report. We identified a number of items that may require document changes, additional research and/ or data validation. Please see our suggestions below. The Siemens Mobility Division provides answers with its comprehensive portfolio; because modern, interconnected and IT-based mobility is the core competency of its five business units: Mobility Management, Turnkey Projects & Electrification, Mainline Transport, Urban Transport and Customer Services. They have the know-how to make road traffic in the US flow more smoothly and quickly, make trains more environmentally friendly and efficient, make train schedules and freight shipments more reliable. We work with our customers to develop optimal solutions to help overcome their challenges. Siemens manufactures light rail vehicles, Tier 4 passenger locomotives and passenger coaches for various customers throughout the US in Sacramento, CA. 1) Page ES-10: 11. Last bullet point: Fully electric locomotives are powered by an electric overhead line, not "charged" as mentioned in the report. 2) Page ES-10: Bottom of the page, last sentence as well as V-11: Please specify what CARB is referring to with providing a "supply network" for the urea required by SCR systems. Based on our experience in the Tier 4 passenger locomotive market, suppliers exist and are ready to supply urea. Supply likely will leverage the current diesel supply chain to railroads. 3) Page I-6: Last sentence: Figure I-6 shows one example of a Tier 4 passenger locomotive, not "the new generation of Tier 4 passenger locomotives" as stated in the document. We suggest to update the sentence to include information on the Siemens Charger locomotives which are currently being built in Sacramento, CA. https://w3.usa.siemens.com/mobility/us/en/interurban-mobility/rail-solutions/high-speed-and-intercity-trains/Documents/Multi-State_Charger%20DE%20Locomotive_DataSheet_LR.pdf http://www.railwaygazette.com/news/traction-rolling-stock/single-view/view/siemens-shows-first-complete-charger-locomotive.html 4) Page VIII-3: Last sentence of first paragraph: "Therefore, all-electric freight locomotives have significantly less pulling power (i.e., up to two-thirds less – though they are typically higher horsepower for speed) than U.S. diesel-electric freight interstate line haul locomotives." --> This statement is not correct and should be removed. 5) Page VIII-5: The 1999 paper from Bharat Bhargava appears outdated and does not include any of the more recent achievements, e.g. in China. This section should be updated or removed. E.g. the Siemens HXD1 9,600kW electric freight locomotive in Datong, China operates at 25 kV/ 50 Hz AC. 6) Page VIII-8: Entire section D. Capital Costs: Locomotives and Infrastructure should be updated or removed. As stated in the document, CARB has limited access to relevant capital cost information. To our mind, publishing a capital cost estimate based entirely on staff opinion and without a meaningful calculation does not appear useful. The available data seems unreasonably high which cannot be validated without a transparent data baseline. It is also not clear from the document, why an increase to a 75kV or a 100kV system may be required. If more information should be available, we recommend to include it. ("Staff has no capital cost information for freight rail electrification in the U.S. We have looked at prior studies that attempted to estimate costs for freight rail electrification in the South Coast Air Basin. Staff has also looked at passenger electrification costs in the U.S. to gain some insights on the order of magnitude of potential costs for freight rail electrification. Finally, staff does not have access to detailed operational and maintenance costs for U.S. diesel-electric or other countries all-electric freight locomotives. Similarly, we do not have access to that information for all-electric rail infrastructure.") Thank you very much for your consideration. Please feel free to contact us with any questions regarding these comments. With best regards, Rolf Neuhaus Siemens Industry, Inc. |
