If they track better they might be worth it. I sold my BLMA sets years ago because of tracking issues I didn’t have time to address.

I got what I thought a great deal for a BLMA 5-car set, only to discover that keeping them on the rails, even with weighted trailers, was far more work than the time spent assembling the hitches. They looked great, however, and I was able to let them go without a loss.
