Sec. 236.14  Spring switch signal protection; requirements.



    (a) The indication of signal governing movements from siding to main 

track with the current of traffic on track signaled for movements in 

only one direction through a spring switch in automatic block signal 

territory shall be not less restrictive than ``Proceed at Restricted 

Speed' when the block, into which movements are governed by the signal, 

is occupied, and shall be ``Stop'' when the main track is occupied by a 

train approaching the switch within at least 1,500 feet in approach of 

the approach signal located stopping distance from the main track signal 

governing trailing movements over switch, except that the indication may 

be caused to be less restrictive if approach or time locking is used.

    (b) The indication of signal governing movements against the current 

of traffic from the reverse main of main tracks to a single track, or 

signal governing movements from a siding to a main track signaled for 

movements in either direction, through a spring switch, in automatic 

block signal territory, shall be not less restrictive than ``Proceed at 

Restricted Speed'' when the block, into which movements are governed by 

the signal, is occupied by a preceding train, and shall be ``Stop'' when 

the block on the single track into which the signal governs is occupied 

by an opposing train.

    (c) The indication of signal governing movements against the current 

of traffic from the reverse main of main tracks to a single track or 

signal governing movements from a siding to a main track signaled for 

movements in either direction through a spring switch in automatic block 

signal territory shall be ``Stop'' when the normal direction main track 

of the double track or the single track signaled for movements in both 

directions is occupied by a train approaching the switch within at least 

1,500 feet in approach of the approach signal located stopping distance 

from the main track signal governing trailing movements over switch, 

except that indication may be caused to be less restrictive if approach 

or time locking is used.
