MLW M-640: The first, second and fourth citations do not refer to the MLW M-640 at all as far as I can tell.  They reference the Canadian Pacific 4744 and then only in passing.  Not sure about the third citation.  If the third citation does go into any any depth, one in depth citation by itself by itself is not enough to establish notability.  Given the track record of this IP user I highly doubt the third citation does reference the subject in an depth, if at all.  This does not pass WP:GNG as it has no independent notability outside of the Canadian Railway Museum.  Suggest a redirect to Canadian Railway Museum .

"...Development Corporation, Canadian Pacific led the way in 1984, extensively rebuilding Montreal Locomotive Works M640 4744, a conventional D.C. locomotive, into an A.C.-traction testbed. In November 1984, 4744 emerged from CP Rail's Angus Shop, still with its unique 18cylinder, 4000 h.p. Alco 251 engine, but with its electrical and control systems radically altered.
