I have a question regarding the 2353T Santa Fe F3 AA units. I've only ever had Lionel steam locos but came across a really clean unit with the box but it didn't include pictures showing under the chassis, nor did it indicate if it was powered or not. I thought I'd done enough research to identify if it was a powered unit or the dummy, but I guess I was the dummy. I won the bid (still for a great price) and once I received it, I realized it's the dummy unit, with no whistle/battery compartment.
Ultimately, my goal is to find a nice, powered unit to complete the pair, but I need some help to ensure I can identify and get the correct powered unit to match.
I guess my confusion comes from being able to identify a powered unit from the dummy in an AA set when they're not together. I've seen several on eBay that have the whistle and battery compartment in the powered unit, and some that seem to have it in the dummy unit. I'm also confused as to where I should find the lever for the 3-position e-unit. In some pics I see it in the center near the battery compartment of the dummy unit but have yet to see a clear picture of where it is on a powered unit.
Any suggestions?
