So I found an N-scale Bachmann Spectrum Nickel Plate Road tender with a healthy price reduction and bought it, thinking along the lines of 'With this I can probably take various steam locos produced in different road names and make them into NKP locos'. 

I was wondering if anyone has tried attaching this tender to the Bachmann 2-6-2 (which I have one of already, but which the Nickel Plate Road never did, so far as I can tell from the Historical Society's steam roster), or, to the Bachmann 0-6-0?

Spookshow says you can attach it to the 2-6-2 and what he's done there (unscrewing the tender, turning the drawbars upside down to bring them into line with the connection point on the loco) looks just about within my powers. 

However if possible I'd like to attach it to the 0-6-0 instead - reason being NKP 0-6-0s actually existed, and that over here in Blighty the 0-6-0 comes up for sale a lot (if someone's selling American N Scale over here, they've usually got that and a PA both in Union Pacific dress). So I get to avoid our old fiend, postage costs.  

What I'm trying to work out is, with the 0-6-0, how the power gets from tender to motor - on my 2-6-2 in front of me I can see there's a conductive block wrapped around the rear axle of the loco that brushes against the drawbars that take power from the tender, but on the 0-6-0 that space is empty. What am I missing? Does the power from the tender just run up the connecting peg and into the loco?
