With PS1 or PS2, I could swap the tender of a steamer with the engine of another steamer and run everything without trouble, being that I kept PS1 with PS1 (4 pin tether), and PS2 with PS2 (10 pin tether), or course. With the PS3 drawbar engines, can you do the same thing with various steamers, or are they each wired up uniquely? Just curious.
Thanks.
