The adaptability of thesteel rope reel can not be over emphasized as its sphere of useful-ness includes its usage in producing a strong pull wherever desir-ed. Rack-Hail Locomotives. Hauling a trip of cars on comparatively level track isrelatively easy, it being necessary to overcome only the resistanceof the train and track. On steep grades however, upgrade haulageis very difficult, in an much as the locomotive not only has toovercome the resistance attendant to level track haulage, but italso has to virtually lift the whole train more or les
