DEFINITIONS
For the purpose of this report, the following definitions apply:

INSTRUCTIONS
Not later than April 1, 1997 and every 5 years thereafter, each
carrier shall file with FRA a signal system status report.

Automatic Block Signal System (ABS) – A block-signal
system wherein the use of each block is governed by an
automatic block signal, cab signal or both.

Show total road and track mileage, to the nearest mile, for
each method of operation.

Automatic Cab Signal System – A system that provides for
the automatic operation of the following:

Show total number of interlockings, controlled points and
switch arrangements on entire system.

(a) Cab Signal – a signal located in engineman’s
compartment or cab, indicating a condition affecting
the movement of a train and used in conjunction
with or in lieu of block signal, and
(b) Can Indicator – a device located in the cab that
indicates a condition or a change of condition of
one or more elements of the system.
Automatic Train Control System – A system so arranged
that its operation will automatically result in the following:
(a) A full service application of the brakes that will
continue either until the train, is brought to a stop,
or, under control of the engineman, its speed is
reduced to a predetermined rate.
(b) When operating under a speed restriction, an
application of the brakes when the speed of the train
exceeds the predetermined rate and which will
continue until the speed is reduced to that rate.
Automatic Train Stop System – A system so arranged that
its operation will automatically result in the application of the
brakes until the train has been brought to a stop.
Non-Automatic Block Signal System – A term used to
denote any method of maintaining an interval of space
between trains as distinguished from an automatic block signal
system, a traffic control system, an automatic cab signal
system without roadway signals, or the time interval system.
Examples would include Direct Traffic Control (DTC), Voice
Control System (VCS), Form D Control System (DCS), etc…
Remotely Controlled Interlocking – An arrangement of
signals and signal appliances operated from an interlocking
machine, which is located outside the interlocking limits, and
so interconnected by means of mechanical and/or electric
locking that their movements must succeed each the in proper
sequence, train movements over all routes being governed by
signal indication.
Switch Arrangement – A term to denote the use of switch
machines, other than hand-operated type, as independent
wayside appliances exclusively in dark territory.

Each railroad should report its own track of jointly operated
track under any of the method of operation and attention
called to the fact that the track is jointly owned each road
should report an equal percentage of the total mileages.
Lines over which a company has trackage rights should be
included only by the operating company.
It is not necessary to report separately the miles of single track
and miles of double track included under any method of train
operation.
Report, on this form, all installations if automatic train stop,
train control, and cab signal systems on the line of the
reporting carrier, including foreign locomotives and motorcars
which operate over these installations.
Multiple unit type cars should be reported as motorcars.
Where the mileage listed is equipped with more than one type
of roadway device show by footnotes any duplication of
mileage.
Equipped by Foreign Carrier. Show the number of
locomotives equipped by foreign carrier for operation
exclusively over reporting carrier’s installation with devices
indicated in the column headings (include both locomotive
equipped for forward operation only and motorcars equipped
for either direction operation). Identify the foreign carrier by
initials.
Foreign carrier locomotives and motorcars may be shown in
“Remarks” column.
A system map, color-coded, to show location of method of
operation on reported mileage, including automatic train
control, cab signal or train stop systems as in service, must
accompany this form and subsequent forms when changes
occur.
Additional copies of this form will be furnished upon request
to the Federal Railroad Administration, Office of Safety, 1200
New Jersey Avenue, S.E., Third Floor West, Washington, D.C.
20590.

Track Operated Jointly – Track that is jointly owned or
jointly controlled and operated by two or more companies.
Trackage Rights – The right to use track over which one
company exercises exclusive control of operation, but permits
another company to operate trains over it, subject to the rules
and regulations of the controlling company.
Traffic Control System (TCS) – A block-signal system under
which train movements are authorized by cab signals or block
signals whose indications supersede the superiority of trains
for both opposing and following movements on the same
track.
