Long hood forward
From Wikipedia, the free encyclopedia
Long Hood Forward (LHF) is a practice of Norfolk Southern's predecessors Southern Railway (SOU) and Norfolk & Western (NW). When the Southern Railway tested the first EMD GP7 they came with a high nose and they pointed the locomotive LHF for crew safety. After the first GP7 hit the Southern Railway System, subsequent locomotives were ordered with the high hood and the long hood designated (Started after the SD45 order) as the front. The term "Long Hood Forward" comes from the two sections of a hood unit. Here is a list of each locomotive Southern ordered with the High Hood, LHF.
General Motors Electro Motive Division GP7, GP9, GP18, GP30, GP35, GP38, GP38-2, GP40X (SOU 7000-7002), GP49 (SOU 4600-4605), GP50 (SOU 7003-7092), SD7, SD9, SD35, SD40, SD40-2, and SD45 (note: the SD50 and the GP59 are the first units ordered with the short hood, and pointed LHF)
General Electric Transportation Systems B30-7, U23B, B23-7, U30C, U30B, U33C, and U36-7
The Norfolk and Western Railway (N&W) did copy off the Southern by doing the same options and the long hood designated as front, the only difference between the N&W locomotives and the Southern Railway locomotives was the position of the bell; N&W had the bell on the short hood while Southern had the bell on the long hood.
