Another source of very fine track detail parts (tie plates, spikes, throw rods, fish plates, etc) is Proto:87 Stores, http://www.proto87stores.com/p87stores/index.htm
And no, not all their stuff is Proto:87 - even some N scale stuff. Much of it will work very well with NMRA-spec track and turnouts. New stuff being added to the line all the time.
my thoughts, your choices
