The Z-iron was 5 inches high and weighed 45 pounds tothe yard. The track consisted of longitudinal under sills, which sup-ported the cross ties, 3£ by G inches and 7 feet long. The wooden por-tion of rail was made to fit closely against the stem and under the headof the Z-irou, to which it was joined by five-eighths inch bolts with screwnuts. The iron and wood stringer was laid to i4 break joints, so that nosplice bars except a base plate was needed at the joints. A section of an ingeniously devised all-iron compound rail laid on theBaltimore and Ohio Kail road in 1848 is shown in Fig. 56. A section ofthe original rail is in the collection.
