What is Automatic Block Signal? | A block signal that is activated either by track circuit or in conjunction with interlocking or Controlled Point Circuits. This block signal automatically indicates track condition and black occupancy. |
What is (ABS) Automatic Block Signal System? | A block signal system in which the use of each block is governed by an automatic block signal, cab signal, or both. |
What is a Block? | A length of track with defined limits on which train movement are governed by block signals, cab signals or Form D. |
LIMITED CLEAR | Proceed at Limited Speed until entire train clears interlocking limits or turnouts, then proceed at Normal Speed. In CSS tenritory with fixed automatic block signals trains not equipped with operative cab signals must approach the next signal at Limited |
ADVANCE APPROACH | Proceed prepared to stop at the second signal Trains exceeding Limited Speed mustbegin reduction to Limited Speed as soon as engine passes the Advance Approach signal. |
APPROACH | Proceed prepared to stop at the next signal. Trains exceeding Medium Speed must begin reduction to Medium Speed as soon as the engine passes the Approach Signal. |
APPROACH LIMITED | Proceed approaching the next signal at Limited Speed. |
APPROACH MEDIUM | Proceed approaching next signal at Medium Speed. |
APPROACH NORMAL | Trains without operative cab signals must proceed on fixed signal indication not exceeding 79 MPH. |
APPROACH SLOW | Proceed prepared to stop at the next signal. Trains exceeding Medium Speed must begin reduction to Medium Speed as soon as the engine passes the Approach Signal. |
CLEAR INDICATION | Proceed not exceeding Normal Speed. RULE 281b. |
CLEAR TO NEXT INTERLOCKING | Trains without operative cab signals must proceed on fixed signal indication, not exceeding 79 MPH, and approach next interlocking signal prepared to stop. |
MEDIUM APPROACH | 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. |
MEDIUM APPROACH MEDIUM | Proceed at Medium Speed within interlocking limits approaching the next signal at Medium Speed. |
MEDIUM CLEAR | Proceed at Medium Speed until entire train clears interlocking limits or spring switches, then proceed at Normal Speed. In CSS territory with fixed automatic block signals, trains not equipped with operative cab signals must approach the next signal at p |
RESTRICTING | Proceed at Restricted Speed until the entire train has: 1. Passed a more favorable fixed signal. or 2. Entered non-signalled DCS territory. or 3. Passed a location where a more favorable cab signal was received. |
SLOW APPROACH | Proceed prepared to stop at the next signal. Slow Speed applies within interlocking limits or through turnouts, then Medium Speed applies. |
SLOW CLEAR | Proceed at Slow Speed until entire train clears interlocking limits or turnouts, then proceed at Normal Speed. In CSS territory with fixed automatic block signals, trains not equipped wth operative cab signals must approach the next signal at Medium Speed |
STOP AND PROCEED | Stop, then proceed at Restricted Speed until the entire train has: 1. Passed a more favorable fixed signal. or 2. Entered non-signaled DCS territory or 3. Passed a location where a more favorable cab signal was received. |
