Norfolk Southern Railway Develops Plug-in Electric Locomotive
The NS999 is a 1,500 horsepower locomotive. Norfolk Southern will use it to move cars around the rail yard. 1,080 rechargeable 12-volt lead acid batteries store about a day's worth of power. The batteries add to their plug-in charging by charging with the energy from breaking.
Implications - By the end of this year, the VP of operations planning and support on the project claims the railway company will have built an over-the-road version of the locomotive with more batteries. Running first with a couple of diesels which wil help recharge the eco-train's batteries, Gerhard Thelan anticipates that eventually the battery engines will power a train by themselves.
