The AAR wheel arrangement system is a method of classifying locomotive wheel arrangements that was developed by 
the Association of American Railroads {AAR}  (including third rail electric locomotives). It is not used for Steam Locomotives which use the Whyte Notation System instead.   The AAR system counts axles instead of wheels. Letters refer to powered axles, and numbers to unpowered (or idler) axles. "A" refers to one powered axle, "B" to two powered axles in a row, "C" to three powered axles in a row, and "D" to four powered axles in a row. "1" refers to one idler axle, and "2" to two idler axles in a row. A dash ("–") separates trucks, or wheel assemblies. A plus sign ("+") refers to articulation, either by connecting bogies with span bolsters or by connecting individual locomotives via solid drawbars instead of couplers.   "B-B" means there are two identical trucks. Each truck has two powered axles, a currently popular configuration used in high-speed, low-weight applications such as intermodal trains.  High speed (" Time ") freight trains, with guaranteed schedules often use B-B locomotives of 3,800 HP (950 HP per axle), but this application, too, has largely been replaced by higher-powered, 4,500 HP C-C locomotives (750 HP per axle). An American colloquialism of B-B is "Four-Axle".   "2-B" means there are two trucks, or wheel assemblies. The "2" truck is under the front of the unit, and has two idler axles in a row. The "B" truck is under the rear of the unit, and has two powered axles. Examples include the three lightweight powered cars built ay ALCO in 1935-37 for use with the Rebel Streamliners.  ** See Wikipedia AAR Wheel Arrangements
