Abstract
Abstract A railway signalling system is disclosed in which there is a combination of fixed block signalling with direct communication between separate trains or vehicles to achieve inter-vehicle spacing. The fixed block signalling prevents more than one train (or vehicle) from transmitting and more than one train (or vehicle) from acting upon communications relative to a given area or portion of line.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
60 words
A railway signalling system in which there is fixed block signalling in combination with direct communication between separate trains or vehicles to achieve inter-vehicle headway spacing, the fixed block signalling preventing more than one train (or vehicle) from transmitting and more than one train (or vehicle) from acting upon communications relative to a given area or portion of railway line.
Claim 2
Dependent Claim
60 words
A railway signalling system in which there is fixed block signalling in combination with direct communication between separate trains or vehicles to achieve inter-vehicle headway spacing, the fixed block signalling preventing more than one train (or vehicle) from transmitting and more than one train (or vehicle) from acting upon communications relative to a given area or portion of railway line.
Claim 3
Dependent Claim
16 words
A system as claimed in claim 1, wherein the fixed block signalling uses track circuit signalling.
Claim 4
Dependent Claim
15 words
A system as claimed in claim 1, wherein the fixed block signalling uses radio signalling.
Claim 5
Independent Claim
28 words
A system as claimed in any preceding claim, wherein the authority to transmit, receive and act upon vehicle to vehicle communications is contained in fixed block movement authorities.
Claim 6
Dependent Claim
38 words
A system as claimed in claim 4, wherein said block movement authorities are given by track circuit code, radio, inductive loop or other means with or without fixed information read from trackside transponders, beacons, loops or the like.
Claim 7
Independent Claim
41 words
A system as claimed in any preceding claim, wherein the direct vehicle to vehicle communication messages convey the location of the tail of a train (or vehicle) expressed as a distance which is interpreted as being beyond a particular reference point.
Claim 8
Independent Claim
21 words
A system as claimed in any preceding claim, wherein the direct vehicle to vehicle communication is by radio or inductive loop.
Claim 9
Independent Claim
44 words
A system as claimed in any preceding claim, wherein, on a train (or vehicle), functions are controlled by a train (or vehicle) computer at the front of the train (or vehicle) or divided between front and tail end equipment of the train (or vehicle).
Claim 10
Independent Claim
21 words
A system as claimed in any preceding claim, wherein the tail location of a train (or vehicle) is deduced and monitored.
Claim 11
Dependent Claim
33 words
A system as claimed in claim 9, wherein the tail location of a train (or vehicle) is deduced and monitored by a train (or vehicle) line or a train (or vehicle) tail device.
