20,985. Johnston, J. Oct. 20. Rails; rail joints.-Grooved tram rails are built up of the rail A and the guard rail B of the section shown, or of other section laid to break joint. Fishplates C may be placed at the joints of either section, and may be secured by well-fitted bolts to increase the conductivity. Copper bonds may thus be dispensed with on electric tramways.
