the speed of the train exceeds the predetermined rate.
✔✔ACSES Controlled Train - ✔✔A passenger or Freight class train equipped with the
following ACSES controlled apparatus: A Data Radio, Aspect Display Unit, sealed
ACSES valve or switch, audible warning device and acknowledging switch in operative
condition
✔✔Foul Time - ✔✔A method of establishing working limits on a main track, secondary
track or siding in which a roadway worker is notified by the Train Dispatcher through the

controlled by the Train Dispatcher or Block Operator by physically preventing the entry
and movement of trains.

trained on roadway worker protection whose sole duty is to provide at least 15 seconds
advanced visual and auditory warning of approaching trains or on-track equipment to
roadway workers.
✔✔Working Limits - ✔✔A segment of track with definite boundaries upon which trains
may move only as authorized by the roadway worker in charge of that segment of track.
✔✔Limited Speed - ✔✔A speed not exceeding 45 mph.
, ✔✔Maximum Authorized Speed (MAS) - ✔✔The highest speed that is permitted over a
specific portion of the railroad, it may be authorized by the special instructions of the
current timetable, rules of the operating department or any other publication authorized
by the general superintendent - transportation
✔✔Medium Speed - ✔✔A speed not exceeding 30 mph, except in ASC territory, train

✔✔Reduced Speed - ✔✔A speed at which a train can be stopped short of another train
or obstruction.
✔✔Restricted Speed (RS) - ✔✔A mode of operation, at which a train can be stopped
within one half the range of vision, short of the next signal, another train, obstruction,
derail, or switch improperly lined, looking out for broken rail or crossing protection not
functioning, not exceeding 15 miles per hour.
✔✔Slow Speed - ✔✔A speed not exceeding 15 mph, except in ASC territory, train will
be governed by speed displayed on the cab signal indicator not to exceed 30 mph.
✔✔Automatic Safety Switch - ✔✔A switch identified by a yellow switch stand. Trains
may make trailing point moves through the switch without previously aligning it by hand
unless otherwise specified.
✔✔Crossover - ✔✔A track connection between two adjacent, not necessarily parallel
tracks, consisting of a minimum of two switches, which is intended to be used primarily

accidents.
✔✔Dual Control Switch - ✔✔A power-operated switch also equipped for hand
operation.
✔✔Electric Lock Switch - ✔✔A hand-operated switch equipped with an electrical device
that restricts the movement of the switch.
