[Elecraft] Self-fusing liquid electrical tape

[Fred Jensen]

I'm colorblind.  If you're talking about the doobers at the end of each 
tie over the foot of the rail, they're hold downs for the rails on 
concrete ties.  They take the place of spikes in wood ties whose purpose 
is to maintain proper separation ["gauge"] between the rails.  The rails 
stand up by themselves.
