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.
1A-A1
"1A-A1" means there are two trucks (or wheel assemblies) under the unit. Each truck has one powered axle, and one idler axle, with the idler axles to the outside. Examples include Budd RDC Diesel MU (DMU) cars.
In rail transport, a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive. Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted notations varying by country. Within a given country, different notations may also be employed for different kinds of locomotives, such as steam, electric, and diesel powered.
Especially in steam days, wheel arrangement was an important attribute of a locomotive because there were many different types of layout adopted, each wheel being optimised for a different use (often with only some being actually "driven"). Modern diesel and electric locomotives are much more uniform, usually with all axles driven.
The Aare (German pronunciation:[ˈaːrə]) or Aar is a tributary of the High Rhine and the longest river that both rises and ends entirely within Switzerland.
Its total length from its source to its junction with the Rhine comprises about 295 km (183 miles), during which distance it descends 1,565m (5,135ft), draining an area of 17,779km2 (6,865sqmi), almost entirely within Switzerland, and accounting for close to half the area of the country, including all of Central Switzerland.
There are more than 40 hydroelectric plants along the course of the Aare River.
The Aar is a 60-kilometre-long (37mi) river in western Germany, left tributary of the Lahn. It rises in the Taunus mountains, near Taunusstein. It flows generally north through the towns Taunusstein, Bad Schwalbach, Aarbergen and Hahnstätten. It flows into the Lahn in Diez.
Name
The name Aar is a common name of rivers and brooks in German-speaking Central Europe, as exemplified by the similarly named tributary to the same Lahn river Aar (Dill). The pre-German word Aar means "quick-flowing water", in a metaphorical sense "small river in a space between mountains". It is commonly conserved in southern German-speaking areas in settlement names ending with -ach.

Welcome back to Railroad 101 - the educational series where we look at all things that make up the railroad. This time we're looking at steam locomotive wheel arrangements - what they are, why they are, and probably 99% of the varieties that were in the USA back in the day.

Train Terms Talk Show Episode 35 SPEICAL: Steam locomotives and the Whyte Notation
Today we are going to talk about something a little out of the ordinary. Instead of talking about diesel locomotives like we have done for the past 2 and a half years, we are finally going to talk about steam engines. Including the way that the wheel arrangements are classified. called the Whyte notation. It is like the AAR wheel arrangements but waayy easier to understand. We also uncover some interesting facts about steam locomotives including what kind of engine the Polar Express is. If you would like to learn about the other method of wheel arrangements for diesel locomotives (AAR) here is a link right here for you to watch after this. Enjoy!

D&H RF-16 review
The BLH RF-16 is a 1,625-horsepower (1,212 kW) cab unit-type diesel locomotive built for freight service by the Baldwin-Lima-Hamilton Corporation between 1950 and 1953. All RF-16s were configured with a B-B wheel arrangement and ran on two AAR Type B two-axle road trucks, with all axles powered. A total of 109 cab-equipped A units were built, along with 51 cabless booster B units, for a total of 160 locomotives built. As was the case with most passenger locomotives of its day, the RF-16s came equipped with a retractable, nose-mounted drop coupler pilot. Unlike competing units from EMD and Alco, the RF-16 used an air-powered throttle, meaning that it could not be run in MU operation with EMD or Alco diesels without special MU equipment.

By August 1974, all but two of the Monongahela Railway units, what were to become 1205 and 1216, had been sold for scrap. The final pair were to be scrapped by GE, but were saved when the Delaware and Hudson Railroad purchased both units from the scrap dealer in exchange for an equal value of scrap steel. They were used in freight service and in passenger excursion service on the D&H until April 1978.
