I use Whal clipper oil, not on locomotives, but in VERY LIGHT applications on track for cleaning and eleictrical conductivity. It works like magic.

I’ve used it before, but I’m not sure if it is worth the trouble. Yes it improves electrical contact, but any oil also attracts and collects dust and dirt. Eventually you will not only need to clean the rails, but also the wheels on a lot of cars.
This is why I say use a very LIGHT application. I put a small amount on and old sock and let it soak in well, then rub that over the rail. The application is extremely little oil, not enough that I have ever had a problem with dirt buildup, but it still improves conductivity.

The trick for me is to lightly apply it to 2000’ of 3 rail O gauge track, some of which is hidden. I also have a lot of locomotives with rubber tires, and I’m not sure if the oil is melting the tires. I’m building a new layout using the track form the old layout, and cleaning as I go. I’ll have to see about using the oil again, I still have plenty. When I clean the rails, it takes a lot of work to remove the black film.
There is a specific lubricant track cleaner by Aero-Locomotive Works, a division of Aero-Car Tech
that is claimed to leave a conductive fillm that will enhance current flow. Further claims to be excellent with DCC & sound systems. It’s an eight ounce bottle for approx $9.00 + ship. I’m
looking at the bottle now as I make this report. I’m not into all this high tech stuff so I cannot attest
to it’s claim.
Can’t find their web page but they are in Western Springs Illinois.
The clipper oil is pretty mild so I don’t believe it would melt your traction tires, but it would somewhat reduce the traction and thus defeat the purpose of the tires in the first place. This could cause slippage which could melt your tires. Either way, I’m sure you’re right about the oil and traction tires not being a good combination. The oil may still help conductivity on the center rail of 3 rail track, however.
