[quote user="wjstix"] <p>[quote user="loathar"]<strong>dehusman</strong> -I think you named em all except one. What does B stand for? As in B-23-7.[/quote]</p><p>This is a GE (General Electric) engine. In general B and C are used in describing diesels by the axles or wheels, the same way a steam engine (regardless of builder) could be a 4-6-0 or a 2-8-2. A means one axle that is powered. B means a diesel's truck has two axles, both powered. C means the truck has three axles, both powered. So a GP or an F-unit is B-B, an SD is C-C. A number means an axle that isn't powered, so for example A-1-A means the truck has three axles, the two outside ones are powered but the middle one isn't - this was done on some passenger diesels like GM's E-units.</p><p>Anyway, in GE's naming system, they use B or C to indicate the trucks the engine has, so if I remember correctly "B-23-7" would mean an engine with two two-axles trucks, 2300 horsepower, and "-7" is the...well let's say "generation"...the "dash 7" line was replaced with the "dash 8" then "dash 9", like the C-44-9W (W meaning "wide" or comfort cab.) Sort of an improved model of the line.</p><p>BTW GMD was GM's affiliate in Canada, building GM diesels under license - even some GM engines made for the US market were made there. </p><p>[/quote]</p><p><strong>This is a quick and neat source of wheel arrangement information:</strong></p><p><a href="http://en.wikipedia.org/wiki/AAR_wheel_arrangement">http://en.wikipedia.org/wiki/AAR_wheel_arrangement</a></p><p><strong>Not only were/are GM locos built in Canada, but as of 1991 the large EMD producer stopped loco production in the USA....and all EMD locos are now built in London, Ontario in Canada....and the company now owned by an investment group and has nothing to do with the old GM ownership...see wiki article below. There is not much romance left in the railroading industry.</strong></p><p>General Motors sells the Electro-Motive Division</p><p>In June 2004, <em><a href="http://en.wikipedia.org/wiki/The_Wall_Street_Journal">The Wall Street Journal</a></em> published an article indicating that EMD was being put up for sale. On <a href="http://en.wikipedia.org/wiki/January_11">January 11</a>, <a href="http://en.wikipedia.org/wiki/2005">2005</a>, <a href="http://en.wikipedia.org/wiki/Reuters">Reuters</a> published a story indicating that a sale to "two private U.S. equity groups" was likely to be announced "this week".</p><p>Confirmation came the following day with a press release issued by GM. General Motors has agreed to sell its Electro-Motive Division to a partnership led by <a href="http://en.wikipedia.org/w/index.php?title=Greenbriar_Equity_Group&action=edit">Greenbriar Equity Group</a> LLC and <a href="http://en.wikipedia.org/w/index.php?title=Berkshire_Partners&action=edit">Berkshire Partners</a> LLC. The newly spun-off company is called Electro-Motive Diesel, Incorporated, which retains the <strong>EMD</strong> brand that is so widely known in the railroad industry. The sale closed on <a href="http://en.wikipedia.org/wiki/April_4">April 4</a>, <a href="http://en.wikipedia.org/wiki/2005">2005</a>.</p>
