Sec.  236.16  Electric lock, main track releasing circuit.

    When an electric lock releasing circuit is provided on the main 
track to permit a train or an engine to diverge from the main track 
without time delay, the circuit shall be of such length to permit 
occupancy of the circuit to be seen by a crew member stationed at the 
switch. When the releasing circuit extends into the fouling circuit, a 
train or engine on the siding shall be prevented from occupying the 
releasing circuit by a derail either pipe-connected to switch point or 
equipped with an independently operated electric lock.
