<p>For: RAILROAD TURNOUTS A railroad turnout including a switch having runoff plates with stop lugs spaced farther apart than the width of the switch point base so that flexure of the switch points downstream of the heel spread is permitted. Floating heel blocks are affixed to the stock rails at the heel point to maintain the conventional heel spread. A smooth ride through the turnout is further assured by additional switch rods, uniform risers in the switch and guard rails associated with the frog of the turnout.</p> |
