Just before dark yesterday on 4/27/18 I spotted these WAMX locos in the yard tied down. Not sure about the heritage of #4121, but the light on the end of the long hood was definitely interesting. Sent from my SM-G955U using Tapatalk
Well, looks like SP speculation on the 4121 is probably correct. Another page shows her heritage as ex SP 8462 (SD40) rebuilt to a SD40-2. The 4163 shows as former CN 5056 (SD40). And since we are at it, 3835 shows as former MP 574 (GP38) Great pictures and nice catch!!!
