Grj,
For once it turned out " it's better to be lucky than skilled" worked out. I downloaded the documentation for the 20-2474-1, they did say to keep the locomotive in the upright position at all times then loosen the truck and let it fall into your hand. I hung the locomotive off the edge of my bench and did just that and luckily for me it worked out. I do have another question since I'm bugging the heck out of you. I want to add PSX-AC's to my layout. I have one Z-4000 wired to my TIU going to 4 track blocks. From the Z-4000 I run a red and black wire to each of the "fixed" inputs to the TIU. I then jumper wires from the 2 "fixed" inputs to the "variable" inputs and change their state to "Fixed". The TIU is powered externally by a Z-750. I've seen threads with PSX-AC's but none exactly like my setup. The threads I saw showed 2 PSX-AC's between the Z-4000 and the TIU. Does that sound right? Or can you point me to the correct thread for my setup?
Many thanks, Don
