Absolutely love this topic—restoring old locomotives is one of the most satisfying parts of the hobby!
One technique that’s worked wonders for me is carefully cleaning and re-lubricating the motor with plastic safe oil. It often brings sluggish engines back to life. I’ve also had good luck using fine sandpaper or a fiberglass pen to clean wheels and electrical pickups. For missing parts, I’ve 3D printed some or scavenged from donor models.
Here’s a recent before-and-after of a 1960s-era diesel I brought back—stripped the old paint, replaced the couplers, rewired the motor, and now it runs like a champ.
Anyone else working on a rescue project?
Would love to swap tips or help troubleshoot!
