Yes, the later Walthers 2-8-8-2's had traction tires. But what if you don't have the later one?
Angus has 2 early-release ones, and some crumbling Rivarossi ones. I am thinking about what his best option is.
Repairing the crumbled frames appears to be a dead end. But he has two good-running Walthers ones,
whose only serious shortcoming is that they can't pull. So, it seems to me that putting a tire on
those might be the best way to solve his problem.
Angus, try the 2-sided tape trick and see what happens. Folks buy that really thin double-sided Scotch tape,
cut a thin strip with a straight edge and a razor blade, and carefully wrap it onto the driver. You could try this
on two geared drivers on your Walthers 2-8-8-2 (one on each engine truck) and see if the pulling improves
to where you want it.
