There is a photo in Steinbrenner's book on page of a DL203 demonstrator dated January 31, 1945. Steinbrenner notes that the two A units were completed in January 1945 and put on test outside the ALCO research laboratory at Schenectady. This stationary testing went on for some time before the units were released for road test on the Delaware & Hudson on September 8, 1945. See The American Locomotive Company A Centennial Remembrance pages 221-230 for the story of the development of the 241 engine and the Black Maria Demonstrators (DL203). --SSW9389 13:23, 4 November 2007 (UTC)
As conceived the Black Maria was originally ALCO specification DL202-1 and DL203-1 for the A and B units equipped with the eight cylinder 539 engine. As built the units were ALCO DL202-2 and DL203-2 with the 12 cylinder 241 engines. Reference is from Rolf Stumpf's page at http://alcoworld.railfan.net/arf.htm and from Steinbrenner on page 179 there is reference to the eight cylinder 539 engine producing 1300 horsepower. --SSW9389 (talk) 17:35, 26 May 2008 (UTC)
The Diesel Shop specifications referenced in this article conflicts with http://www.thedieselshop.us/ALCOdemo.HTML page on ALCO Demonstrators which uses the same Diesel Locomotive (DL) Specification used on Rolf Stumpf's page here http://alcoworld.railfan.net/specindx.htm --SSW9389 (talk) 17:57, 26 May 2008 (UTC)
