Re: 180 off track

Well, the track was worn, the wheelbase was long
(3.66m - 12 ft not 2.74m as the latest edition of
Destination City says - that was the S class), the
truck had probably not been greased for a long time
... take your pick!

The idea of a "Radiax" truck was that the axles could
move a little to follow the curve. If they were not
well greased, then that movement would be that much
less flexible.

I attach a pic of 180's Brill Radiax truck - you can
see how the axle boxes are floating in the middle of a
yoke like casting - with springs to hold them roughly
in position.
