Tien the cable is drawn off as tie locomotive ad-vances, the springs are wound up; when the locomotive returns, thecable is automatically reeled in as the cable springs are uncoil-ed. Thus the cable is always kept taut whether the locomotive isrunning forward or backward or is standing still. The spring reelhas the advantage over the mechanical reel in that sliding or slip-ping of the locomotive wheels can not affect the action of thereel. Provision is made so that the cable may be wound up without. PLATE 30.
