I am lucky to have acquired two of the in the last year at a reasonable price. A KCS and GE Hybrid ES44AC. I was able to get the GE under the 1k price and spent $100 on parts to make it like new again. This poor engine needed a lot of TLC and has ended up a great runner.
For those that have them, do you run them or are they shelf queens and are there any problems to expect with them?
Here are my to ES44AC's.
I do all my own repairs. The few times that I have sent trains back to Lionel to fix they have ether comeback fixed with new problems or fixed with the same problems.
