Altoona Works BP4 : ウィキペディア英語版 | Altoona Works BP4
The Altoona Works BP4 is a B-B battery-electric locomotive rebuilt by the Altoona Works of the Norfolk Southern Railroad. It is the result of a conversion of an existing EMD GP38-type locomotive. This involves replacing the existing prime mover with a set of 1080 12-volt lead-acid batteries, and associated control equipment. ==Overview== Despite appearing somewhat similar to a conventional diesel electric locomotive, the BP4 has no diesel engine; battery charging is provided by plugging in an external power source. Battery life is extended by the use of regenerative braking, which returns power to the batteries. The BP4 is designed to operate 3 shifts on a single battery charge.
