Just wanted to say that I finally attempted and finished my first 'Talgo Upgrade' project on an old car I bought on ebay a while ago for my son. I didn't do it exactly the way that Bob laid out in his excellent post on the subject, I elected to purchase new trucks rather than fool around with the modified talgo (which ended up being a good plan since I broke one talgo while removing it from the car), but the idea was essentially the same.
The trucks are much better (they roll so much smoother than the old ones) and the new Kadee couplers are now compatible with the locomotives we own. It wasn't as hard as I was expecting it to be, but Bob's instruction was critical to motivating me to even try it. Thanks, Bob!
One down, eleven more to go!
Parker,
You're welcome, and congratulations. I'm glad you got one done, the rest will be easy.
I posted an update on the Talgo Upgrade thread you might want to read.
