On thisbasis, the spacing from the center of the last hole to the end ofthe bar would be 3f inches for the 4-bolt splice and 2| inches forthe 6-bolt splice. In Plate VII are shown some of the many designs which havebeen competing for favor and which have been more or lessextensively tried out for both steam and electric railroad many thousands in the aggregate have been placed onvarious roads, no one design has succeeded in displacing the.
