Sources

The best source is the Steinbrenner book that has ten pages on the Alco 241 engine. Next up is Preston Cook. Mr. Cook has written several articles on the Black Maria demonstrators. We need a link to the Alco DL202 article as there is more 241 engine detail there. And additional sources to those demonstrators. --SSW9389 03:46, 10 March 2017 (UTC)
