西门子电池混合动力有轨电车在美国夏洛特市投入运营
西门子交付给美国夏洛特交运系统 (CATS) 的S700 有轨电车现已投入运营。
这些新型有轨电车采用先进的混合技术设计，具有创新的电池存储系统，支持电车以无网方式穿过城市中心，在城市中央商务区保持无接触网区。
每辆有轨电车都采用混合无接触网技术，允许车辆通过车载储能系统 (OESS) 在线和离线运行。OESS 包括可扩展的模块化设计，可以随着电池技术的发展而更新。电池存储和节能技术首先在圣地亚哥进行了展示，当车辆连接到架空接触网系统时，它允许电池充电。这些车辆的运行速度高达每小时 25 英里（时速40），能够搭载近 195 名乘客。
六列新的 S700 有轨电车加入了夏洛特目前由 42 列S70 轻轨车辆组成的轻轨车队，使 CATS 运营的西门子车型总数达到 48 列。
新的有轨电车还包括增强整体骑行体验的功能，例如提高能见度的大型乘客窗户、通过内部监控系统提高乘客安全性以及无障碍地板概念，为自行车存放和轮椅提供更多空间。此外，新车的运营性能增强包括优先通行、行人友好的前罩和基于增强型 3D 红外传感器技术的自动乘客计数器。
这些有轨电车是在 2016 年底订购的，当时夏洛特市选择西门子交通为夏洛特地区交通系统 (CATS) 建造六列新的 S700 有轨电车，该公共交通系统在北卡罗来纳州梅克伦堡县和其他四个周边县运营。这些车辆是在加利福尼亚州萨克拉门托的西门子交通工厂制造的，并且已经全部交付。
夏洛特有轨电车在 CityLYNX 金线的第二阶段运行，取代了目前正在运行的传统绿色和黄色电车。新阶段为金线增加了 2.5 英里，将其长度扩大到 4 英里，并增加了 11 个新站点。
Siemens Mobility battery hybrid operated streetcars enter revenue service in Charlotte, North Carolina
Innovative battery technology allows for hybrid operation on or off-wire
Sustainable technology preserves city’s historic district
S700s were manufactured in Sacramento, CA
Siemens Mobility’s S700 streetcars delivered to the Charlotte Area Transit system (CATS) in the United States are now in revenue service. Designed with advanced hybrid technology that features an innovative battery storage system, these new streetcars run wirelessly through the heart of the city, maintaining a catenary-free zone in the city’s central business district, while offering all the same sustainability benefits as when operating with overhead wires. The six new S700 streetcars join Charlotte’s current light rail fleet of 42 S70 light rail vehicles, bringing the total number of Siemens Mobility vehicles operated by CATS to 48.
“We are delighted to once again partner with Charlotte to help them meet their growing mobility needs by delivering our market leading streetcar platform that incorporates the most innovative and intelligent technologies available,” said Michael Peter, CEO of Siemens Mobility. “Sustainable transportation is one of the most important features for growing cities. Our battery hybrid vehicles provide CATS and its passengers with an energy efficient mobility solution that not only improves the overall availability of transportation, but also offers a comfortable ride and enhanced passenger experience.”
Each streetcar features a hybrid wireless technology allowing the vehicle to run both on and off-wire via an Onboard Energy Storage System (OESS). The OESS includes an expandable and modular design that can be updated as battery technology evolves. The battery-storage and energy-saving technology was first demonstrated in San Diego and allows the battery to recharge when the vehicle is connected to the overhead catenary system. The vehicles operate at speeds up to 25 mph and are capable of carrying nearly 195 passengers.
The new streetcars also include features that enhance the overall riding experience such as large passenger windows for increased visibility, improved passenger safety through an interior surveillance system, and an unobstructed floor concept that allows more space for bicycle storage and wheelchairs. In addition, the operational performance enhancements of the new streetcars include traffic light preemption, a pedestrian-friendly front mask and an automatic passenger counter with enhanced 3D infrared sensor technology.
The streetcars were ordered in late 2016 when the Charlotte City Council chose Siemens Mobility to build six new S700 Streetcars for the Charlotte Area Transit System (CATS), the public transit system operated across Mecklenburg County and four other surrounding counties in North Carolina. The vehicles were built at the Siemens Mobility rail manufacturing hub in Sacramento, California and all have been delivered.
The streetcars for Charlotte run on the second phase of the CityLYNX Gold Line, replacing the legacy green and yellow trolleys currently in operation. The new phase adds 2.5 miles to the Gold Line, expanding it to 4 miles in length and adding 11 new stops.
CATS is one of more than 35 agencies across the United States benefiting from Siemens Mobility’s portfolio of rail vehicles, locomotives, components, and automation systems. American cities also rely on Siemens to provide traction-power substations and electricity transmission, as well as signaling and control technology for freight and passenger rail and transit systems.
