They areusually about {i oi an inch square, and are used for re-moving old bolts and rivets, and in some cases they areused to force the holes in the rail and splice-bars intoline, so that a bolt can be put in, particularly where railsof different sizes are being spliced by a special joint. Track chisels and punches are used in case of emer-gency by the section gang, such as after a wreck, whenthe track must be fixed in the shortest possible time, orin laying a switch. 217. Rail Fork.—A rail fork is used in turning rails. over. The prongs of the fork are slipped over the baseof the rail. Rail forks are made out of mild steel; thegeneral dimensions are as shown in Fig. 129; the slot isI of an inch wide and 4 inches deep, the prongs are Ifinches thick, the lower part of the handle is l|-inchoctagonal steel, and the balance of the handle is round,tapering down to 1-inch diameter at the end, the totallength being 33 inches. Rail forks are not needed often,but they are very convenient and save a great deal oftime in some cases, such as in cutting a rail, in whichcase the rail must be turned repeatedly. 218.
