Why don't conductor rails short out in the show?

David Jones asked the Naked Scientists:
   
Why don't conductor rails on the railways short out when heavy snow connects them not only to the ground beneath but also to the earthed track?

Surely there would at least be a massive current loss due to electrolysis of the snow?

What do you think?
