Model Naming

I've heard the B+B-B+B model referred to as a U50B. Is that correct or just another made-up name for it? -- ckape (talk) 00:34, 15 Jan 2005 (UTC)

Also made up, from the information I have. Appears never to have been used by manufacturer or railroads. It's like the EMD DD35, which gets called the DD35B everywhere because, well, every other B unit has B after it ... —Morven 02:12, Jan 15, 2005 (UTC)
