[edit] DDA-40-X vs. DD40-X

The DDA-40-X Model Designation was created by EMD and used in officially sanctioned maintenance and operating manuals. For example, I have in my possession a 1970 copy of the DDA-40-X Maintenance Manual. However, the UPRR Loco Dept. has preferred to use the DD40-X model designation in all official literature and maintenance records since they began to arrive on the property in 1969. Electrical prints, annual diagram books and LMIs (Locomotive Maintenance Instructions) throughout the 70s and 80s all use the DD40-X designation. This model designation is still in use at UPRR; the maintenance records and UMLER file for the UP#6936 continue to use the DD40-X designation. Sunktanka (T:C) 05:48, 3 January 2007 (UTC)

Generally, we use the manufacturer's official name as the title of an article, but add redirects where appropriate. Since this model was really used by only the UP, this information should be mentioned in the article too. Slambo (Speak) 11:33, 3 January 2007 (UTC)

[edit] #70-80?

Where there ever any DD40's numbered between 70-80? Because i've seen a model version and its either number #78 or #76.User:Trainboy 02:31, 7 March 2008 (UTC)

No, there were no DD40X's numbered between 70 and 80. The locos you are thinking of are DD35A's which were numbered between #70 and #84. There were also cabless versions designated as DD35's that were numbered from #72B to #98B. Sunktanka (T:C) 10:47, 17 March 2008 (UTC)

[edit] Anyone else?

Did any other rail-road use this double engine technology?.User:Trainlover 02:34, 5 March 2008 (UTC)

Most center cab locomotives would have two engines in them, though they are usually much smaller than the DDA40X. n2xjk (talk) 18:18, 18 March 2008 (UTC)
