Hood Unit
A hood unit, in North American railroad terminology, is a body style for diesel and electric locomotives where the body is less than full-width for most of its length and walkways are on the outside. In contrast, a cab unit has a full-width carbody for the length of the locomotive and walkways inside. A hood unit has sufficient visibility to be operated in both directions from a single cab (locomotive), cab. Also, the locomotive frame is the main load-bearing member, allowing the hood to be non-structural and easily opened or even removed for maintenance. History The hood unit evolved from the switcher locomotive. A switcher's long hood is normally low enough that the crew can see over it, and there typically is no short hood. American Locomotive Company, Alco introduced the road switcher concept with the ALCO RS-1, RS-1, which was an enlarged switcher with a short hood ahead of the cab. This was added to provide protection for the crew in case of a collision. The low long ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Long Hood
The long hood of a hood unit-style diesel locomotive is, as the name implies, the longer of the two hoods (narrower sections of the locomotive body in front and behind of the cab) on a locomotive, particularly American-type freight locomotives. Equipment The long hood normally contains the diesel engine (prime mover), the main generator or alternator, the locomotive's cooling radiators, the dynamic brake resistor grids if fitted, and most of the locomotive's auxiliary equipment. Head-end power equipment, if fitted, is normally in the long hood; steam generators for heating older passenger cars may be either in the long or short hoods. Operating direction Normally, the long hood is the rear of the locomotive. For early hood unit models, this was not the case; railroads preferred to run with the long hood at the front and the cab at the rear (referred to as operating long hood forward or LHF). This is a holdover from the steam era of railroads where almost all locomotives were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD GP50
An EMD GP50 is a 4-axle diesel–electric locomotive built by General Motors Electro-Motive Division (EMD). It is powered by a 16- cylinder EMD 645F3B diesel engine, which can produce between 3,500 and 3,600 hp (2,610 and 2,685 kW). 278 examples of this locomotive were built by EMD between 1980 and 1985. BN 3110-3162 were all delivered with five cab seats, the final five of these having the cab lengthened 23 in (584 mm) vs. the standard EMD cab. The GP50 retains the same overall length of 59 feet 2 inches (18.03 meters) as the GP38, GP39, and GP40 series locomotives. History EMD delivered the first GP50s to Chicago Northwestern in the summer of 1980. Much of the GP50's new technology was tested and developed with the experimental GP40X. Changes to the 645F3B engine compared to older versions, include a stronger crankcase, new turbocharger, new plate crab for clamping the power assemblies to the crankshaft, a camshaft of increased hardness, one-half-inch-d ...

EMD GP38-2
The EMD GP38-2 is an American four-axle diesel-electric locomotive built by General Motors, Electro-Motive Division. Part of the EMD Dash 2 line, the GP38-2 was an upgraded version of the earlier EMD GP38, GP38. Power is provided by an EMD 645E 16-cylinder engine, which generates 2,000 horsepower (1.5 MW). GP38-2W The GP38-2W is a Canadian variant of the GP38-2. It is easily distinguished by its wide-nose Canadian comfort cab. 51 of these locomotives were produced for the Canadian National Railway during 1973–1974. Although a W is commonly suffixed to the name, it is actually an addition by enthusiasts to help specify the presence of a CN-spec comfort cab. No locomotives built using CN's design of comfort cab ever featured a W in their designation, as the presence of the cab did not mechanically alter the locomotive. This is reflected by the lack of the "W" in the model designation on the builders' plates of these units. There are snow shields above the inertial-filter cen ...

B Unit
A B-unit, in railroad terminology, is a locomotive unit (generally a diesel locomotive) which does not have a control cab or crew compartment, and must therefore be operated in tandem with another coupled locomotive with a cab (an A-unit). The terms booster unit and cabless are also used. The concept is largely confined to North America and post-Soviet countries. Elsewhere, locomotives without driving cabs are rare. A B-unit is distinct from a slug unit, which only has traction motors and in certain instances may have a cab. The term primarily is applied to freight locomotives, but can be applied to passenger multiple units as well in some cases for when motor cars are put in the middle of trains. In practice however, the term is rarely used to describe multiple unit trains, and in many circumstances the non-cab cars are directly or indirectly permanently attached to a cab car. Controls Some B-units cannot be moved without a controlling unit attached, but most have some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
