Can anyone tell me more about this B unit. Can't find it listed anywhere. I got it with a 2353 A unit with one motor and horn. Greenberg does not list it. What A unit did it come with? Did it come as part of a set? Was it part of an A/B/A configuration? In the Greenberg guides, all I could find is a 2245 which is part of the Texas Special, but mine is a Santa Fe. I also see 2243C listed but not a 2245C. Any information I can get would be appreciated.

Thank you! Much appreciated. Wondering if you could also tell me what I would pair my 2353 (with motor and horn) Santa Fe that I have. Did lionel make a dummy A unit that did not have the horn? I know that for a time they had the horn in the motorized unit and then moved it to the dummy units. I would like to have a complete 2353P/T AA locos.
