The Tanfield Thunderbolt

I recall the Tanfield Thunderbolt epithet being applied to us by the Daily Telegraph about 20 years ago, when our light railway order passed through Parliament.   In further support I offer the existing coat of arms for Stanley.   This shows the Causey or Tanfield Arch, and the bull's Roman shield features thunderbolts, hence the Tanfield Thunderbolts.
