I have a problem with some of my PRS cars with needle point axles. The
axle(s) seems to drift to one side and then stay there. The car will
then stay that way until straighten by hand. Off hand I can't recall
which trucks/wheel combinations cause the problem, but the cars in
question are the ACF grain hopper and the 40' house cars.

The ACE trucks were the only ones to pick that one frog of the

directions compounding the complexity. Pointed axle trucks don't have
any side-to-side movement of the axle in the side frames. And once the
side-play was greatly reduced the picking problem disappeared.

roll almost as free as some of the contemporary trucks on the market.
I have for years tried to locate a source for the brass bearing
inserts, thus far without success. I have used some delrin tubing, but
I still prefer the integrity of the brass ones.

don't guarantee my track laying procedures to9 anybody foolish enough
to try them, but my railroad is derailment free for the most part, in
spite of them.

They sold a spacer with the delrin bearings that you had to slide over
the bearing before inserting into the frames. With .110 wheels there
was still a fair amount of side-to-side slack. This was a problem for
my trickiest track work - a double crossover on a curve- where some of
the cars with ACE trucks picked one frog in one direction only. I
rectified that by sliding some brass washers with an inner diameter
that just fit over the ends of the axles. The pointed axle trucks
never picked that frog.
