A setshould include jacks of 10 to 30 tons capacity, and, at least, one pair shouldbe fitted with claws. They should have thumb-screw releases. The com-mon wrecking frog consists of a heavy bent bar, the upper end of which ispivoted to a support which straddles the rail, the feet of this support andthe free end of the bar having spurs to bite into the ties .or blocking andprevent slipping under a load. With these are used wedges of wood, plated.

Various formsof metal wrecking frogs are used, being placed on or at the side of the rail,as shown in Pig. 224. The organization of the wrecking force is an important is best to have the force in charge of the motive power or operating de-partment, and the gang should be composed of shop men, as they are familiarwith car and engine work, and with the use of tackle in heavy hoisting,while the same men are available in each case and are thus crew of a wrecking train should consist of 15 to 20 men, including aforeman.
