Proceed
Absolute Clear
Proceed; Track clear to next interlocking signal. Approach next interlocking signal prepared to stop
Approach-Medium
Proceed approaching next signal at medium speed
Medium-Clear
Proceed; Medium speed within interlocking limits
Absolute-Medium-Clear
Proceed; Medium speed within interlocking limits. Track clear to next interlocking signal. Approach next interlocking signal prepared to stop
Approach-Slow
Proceed approaching next signal at slow speed. Train exceeding medium speed must at once reduce to that speed.
Approach
Proceed approaching next signal prepared to stop. Train exceeding medium speed must at once reduce to that speed
Caution
Train Exceeding medium speed must at once reduce to that speed. Where a switch is connected with the signal, approach that switch prepared to stop. Approach next signal prepared to stop
Slow-Clear
Proceed; slow speed within interlocking limits
Absolute-Slow-Clear
Proceed; slow speed within interlocking limits. Track clear to next interlocking signal prepared to stop
Slow-Approach
Proceed approaching next signal prepared to stop. Slow speed within interlocking limits
Flashing Slow-Approach
Train will proceed in accordance with signal indication within interlocking limits and after clearing the interlocking, proceed under absolute clear indication to the next interlocking
Restricting

Caution Indicator
Facing point switch(es) open. Trains exceeding slow-speed must at once reduce to that speed approaching switch or switches prepared to stop
Clear Indicator
Facing point switch(es) closed
Yard Switch Indicator
White: Switch normal, proceed at restricted speed
Yellow: Switch reverse, proceed at restricted speed
Red: Switch not normal or reverse, route must be verified. The conductor or engineer must examine the switch points to verify that the points for the rail properly before movement may be made over switch. At restricted speed
Stop Board
Stop then be governed by timetable special instructions, General Notice or Bulletin Notice
End of Block

Spring Switch Marker
Spring Switch
Approach/Distant Signal Marker
Visual reminder to engineers of trains that rules 28B and 33B apply between the distant signal and the home signal
Clearance Point Sign
The location at which equipment must clear to access a track(s) for facing point moves in the opposite direction
Delay in Block Sign
Visual reminder to engineers of rains that rules 28B and 33B Apply when a station stop is made at this station
Permanent Speed Restriction Sign
Reduce speed as prescribed by timetable
Begin MTEA
The location at which MTEA limits begin. Trains must operate in accordance with rule 155
End MTEA

Approach Limited (Zone A)
Proceed approaching the next signal at limited speed
Limited Clear (Zone A)
Proceed at limited speed until entire train clears all interlocking or spring switches
Advance Approach (Zone A)
Proceed prepared to stop at the second signal. Trains exceeding limited speed must begin reduction to limited speed as soon as the engine passes the advance approach signal.
Medium Approach(Zone A)
Proceed prepared to stop at the next signal. Trains exceeding medium speed must begin reduction to medium speed as soon as the medium approach signal is clearly visible
Restricting (Zone A)
Proceed at restricted speed until the entire train has passed a signal displaying a more favorable aspect or entered non-signaled DCS territory
