Ok, so there has not been a post in well over 6 months, and thats because I have been stalled on ONE project. The ALCo S6 from Pee Wee’s Big Adventure. I have not been able to Locate ANY information on it. Can any of my readers help me out with this identity so I can proceed with other projects? Here is a photo that I have of the locomotive
The only markings on this unit is the #11 on the cab. However, none of the SP ALCo switchers were ever numbered in an 1100 series….Help is really needed!

It’s actually Venture County Railroad #11 prior to it being painted into its new scheme. I believe you already did this one.
If it is actually Ventura County RR #11, then it is originally an Alco S6 built as SPRR 4641 renumbered to 1277 in 1965.
That is correct.
That was the VC 11 Ventura county Railway
