Great resource, Tom. I spotted rail anchors in the Accessories section -- check 
out page 4-12. It doesn't really show what their purpose is, so that would be 
good to know if someone has that info.

Rail anchors are also known as anticreepers - they serve to keep the rail from 
moving longitudinally (in a direction perpendicular to the ties).

Apparently this in important everywhere, since one sees them along nearly all 
mainline tracks.  Variations in temperature make them especially important 
along continuous welded rail track - to prevent, or at least reduce the 
occurrences of sun kinks.  And even without the effects of very hot & very cold 
weather, it has been noted for a long time that rail creep can happen under the 
force of trains accelerating & decelerating.  Repeated braking for a station 
and accelerating away from a station will put force on the rail to make it 
move.  

There was an interchange track between the NYC & AA tracks in Ann Arbor MI, 
just above the dam.  It had a steep grade.   They say (could be an urban myth) 
a locomotive struggling up that grade once shot a length of rail out from under 
it.
