摘要

In general, the demand for communications and signal ing (C&S) power supplies was strong in 2010, and it's at high ebb again this year, suppliers say. Just how much of that demand is being driven by the pending implementation of positive train control (PTC) technology is unclear, but the game-changer that is PTC definitely is driving some of it. Some suppliers say railroads are gearing up for the likely increase in remote power requirements for PTC. "Last year was our best year ever, and this year looks every bit as good-especially because of PTC," says Tom Ulrich, president of Arthur N. Ulrich Co., which supplies batteries, chargers and other power equipment to all the Class Is. "It's driving a lot of power needs that weren't there before." Others say railroads are not yet pulling the trigger on pur chases connected to a technology that remains a few years off-or longer, should the federal government extend PTC implementation, as a few suppliers suggest.

Ulrich Co.总裁汤姆·乌尔里希(Tom Ulrich)说,该公司为所有级别的汽车提供电池,充电器和其他电源设备是的。 “这推动了许多以前没有的电力需求。”其他人则表示,如果联邦政府像一些供应商所建议的那样延长PTC的实施时间,那么铁路还没有拉动与这项技术相联系的采购,而这项技术仍需要几年甚至更长的时间。
