Norfolk Southern GP33ECO
The NS GP33ECO is a 4-axle diesel-electric locomotive built by the Norfolk Southern Railway in its Juniata Locomotive Shop. The locomotive is a rebuild of the EMD GP50 designed to meet Tier 3 emissions standards. Norfolk Southern plans to convert a total of 25 GP50s. The first locomotive was completed in January 2015. The rebuild was funded in part by the federal Congestion Mitigation and Air Quality Improvement Program.

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.
Only 1 BP4 has been constructed, Norfolk Southern No. 999, which was converted from GP38 No. 2911 (former Conrail No. 7732).
This conversion significantly alters the external appearance of the locomotive, with the cab (which is actually brand new) being moved forward on the frame to make room for a large louvered battery box, which takes the place of the locomotive's long hood. The fuel tank is similarly replaced with another battery box.
Altoona Works BP4 Overview
On September 28th, Today, Congressman Shuster joined Transportation Secretary Ray LaHood in unveiling a revolutionary new electric locomotive at the Norfolk Southern Juniata works in Altoona. The new engine, developed by Penn State and Norfolk Southern, with funding from Congress and the private sector, will help usher in a new generation of clean and green rail transportation.
