Definitions
- This invention relates to a rail system and, more particularly, a method and apparatus for providing a rail system, such as (but not exclusive) a street-running tram or light rail system.
- Figure 1 shows the prior art.
- Traditionally in order to provide a trackform for rails 34, it is necessary to excavate street 10 (between footpaths 12 having kerb 14) to provide an evelope to contain the sub structure for the trackform and the required High and Low voltage duct banks (often referred to as conduits).
- the width of this envelope is a function of the width of the rail vehicle whilst moving (Developed Kinematic Envelope), the track geometry (vertical, horizontal and cant) and the High and Low voltage duct bank configurations.
- the excavation depth is typically around 1200mm to 1500mm (vertically) below existing road level.
- the High and Low voltage duct banks, 24, 26 are provided, typically either side and outside the trackform. Historically, these duct banks are at greater vertical depth than the rails 34 and would come no closer than 600mm (vertically) to the finished top of rail level.
- the High and Low voltage duct banks 24, 26 are required to ensure the rail system can operate.
- a suitable sub-grade material 20 (to comply with Highways agency or local government specifications for example) is then placed between the ducts 24, 26 if required and a flush surface is provided typically around 500-600mm below the finished top of rail level.
- a rail system comprising an elongate ducting trough located along a swept path, said ducting trough being for housing electrical cables, and at least one rail on which a train or tram runs, said rail being positioned alongside and generally parallel to said ducting trough.
- a method of providing a rail system comprising the steps of providing an elongate ducting trough along a swept path, said ducting trough being for housing electrical cables, and providing at least one rail alongside and generally parallel to said ducting trough.
- the ducting trough and the at least one rail are in substantially the same plane and/or at substantially the same level, in use.
- the ducting trough may, for example, be positioned substantially centrally (with one or more rails being positioned to the side thereof) or it may be positioned at or adjacent the side of the swept path.
- a trough section for use in constructing a rail system, said trough section defining at least one channel for housing electrical cables and being adapted to be positioned generally centrally within a swept path alongside and generally parallel to said at least one rail.
- the trough section has a built-in radius at one or more ends such that two or more trough sections may be positioned adjacent to each other and fit snugly together, even if they are being placed around a curve or bend.
- the or each trough preferably defines at least two channels, one for housing low voltage cables and the other for housing high voltage cables.
- the swept path of the rail system can be relatively shallow, say around 500mm, or so, such that the number of utilities affected by the excavation can be minimised, if not eliminated altogether.
- Means, such as a cantilevered structure, may be provided to carry a feeder pole, such that the need for deep excavation for this purpose is also eliminated.
- the ducting trough, or each trough section is beneficially formed of reinforced concrete. Some sections may comprise unitary structures, whereas one or more others may be provided with an opening at the top having a removable cover, thereby to allow access to the electrical cables housed within the channels.
- a trough having a removable cover is placed at spaced-apart intervals (say every 100m or so) along the length of the rail system.
- An exemplary embodiment of the present invention provides a simplified construction method by providing conduits at a high level, which also provide temporary lateral support to the rails during the construction process.
- a rail system comprising a ducting trough or support member and at least one rail; the rail being positioned along side the ducting trough or support member.
- the rail and ducting trough or support member are positioned at substantially the same depth.
- the rail and the ducting trough or support member are of substantially the same height and/or in substantially the same plane, in use.
- a trough or support section for use in constructing a rail system, the trough or support section having either securing means (or allowing securing means to be attached to it) or defining at least one channel for housing electrical and mechanical cables and equipment and being adapted to be positioned generally along side at least one rail.
- the securing means is a thread, although this is not essential.
- the trough or support section has built in radii at one or more ends such that two or more trough sections may be positioned adjacent to each other and fit snugly together in both the horizontal and vertical planes . (This depends on the construction method, the above is more relevant to pre-cast or "off-site” manufacture, however, cast “in-situ” solutions are equally applicable).
- the trough or support section defines at least two channels, one for housing low voltage cables and the other for housing high voltage cables.
- the trough or support section is at least partially formed of reinforced concrete, composites, resin, or polymer. And it may comprise a substantially unitary structure or a substantially solid structure. Preferably the trough or support section includes electrical cables housed within the channels.
- the trough or support section comprises at least one bar extending outward from the section.
- the rail system has a ducting trough or support member comprising one or more trough or support sections.
- the rail system comprises a depth of construction which is relatively shallow.
- the rail system includes means for carrying electrical or mechanical equipment.
- One means of carrying electrical and mechanical equipment is a cantilever structure.
- the rail system has ducting trough or support member comprising a combination of trough or support sections.
- the rail system has ducting trough or support member having one or more removable covers.
- the rail system has one or more removable covers which are spaced apart at intervals along the length of the ducting trough or support member.
- a method of constructing a rail system comprising the steps or providing an elongated ducting trough or support member substantially positioned along side at least one rail.
- the method of constructing a rail system comprises the steps of laying an elongated ducting trough or support member, then laying a sub-base, positioning at least one rail substantially along side the ducting trough and then pouring a concrete slab. More preferably the at least one rail and ducting trough or support member are positioned at substantially the same depth. Beneficially, the rail and the ducting trough or support member are of substantially the same height and/or in substantially the same plane, in use.
- the method of constructing a rail system comprises the additional step of securing a gauge support frame to the ducting trough in order to position at least one rail.

- the trackform design is based on a single poured Continuously Reinforced Concrete Pavement (CRCP) design conforming with the Highways Agency Design Manual for Roads and Bridges (DMRB).
- CRCP Continuously Reinforced Concrete Pavement
- DMRB Highways Agency Design Manual for Roads and Bridges
- JCP Jointed Concrete Pavements
- CRCR Continuously Reinforced Concrete Roads
- un- reinforced trackforms concrete bearers cast into a trackform, glass fibre (or other fibre) reinforced, or ballasted track.
- a typical street comprises a road section 10 and footpaths 12 running either side of the road section 10.
- Each footpath 12 is generally defined by a kerb 14.
- Drainage gulleys 16 are provided at the interface between the road section 10 and the kerb 14. The drainage gulleys 16 normally connect into respective carrier drains 18 running longitudinally with the street.
- the first step of the method would generally involve excavating a section of the road 10.
- This excavation depth would typically be 500mm deep and uniform across the width of the trackform only.
- the width is a function of the type of rail vehicle, track geometry and other constraints depending upon uniquenesses of the particular location.
- 500mm is a typical figure.
- the 500mm depth would be "saw cut” vertically into the existing highway surface and material to this depth is excavated between the vertical "saw cuts”.
- CBR Californian Bearing Ratio
- CBR's of 15% or higher are attained the bottom of formation will be compacted with suitable construction plant. It should be noted that this invention does not rely on CBR of 15% being achieved; CBR's can be lower, say minimum 5% due to the load path created by a concrete trackform, or other trackforms outlined earlier.
- a ducting trough 22 is positioned along the centreline of the excavation, see Figure 2C. It should be noted however, that the ducting trough 22 may also be placed to either side of the excavation.
- the ducting trough 22 defines two parallel channels 24, 26, one for the Low voltage cables and the other for the High voltage cables. Other cables can also be carried by these apertures.
- the next step of the process involves the placing of a layer of sub base material 27 (of say 150mm depth, fitting flush up to the "saw cut” highway on one side and the trough 22 on the other).
- This material will comply with the DMRB requirements, and will normally be a Cement Treated Basecourse. This material will be well compacted. Other material types may be used.
- a first layer (the bottom layer) of steel reinforcing mesh 28 is placed on top of the sub base material 27, and welded as required for stray current collection purposes.
- the rail 34 is then placed in the excavation and welded to form a continuous length to suit the site conditions.
- two channels can be formed by form work.
- the channels are dimensioned to take a rail of desired section.
- the rail can be placed into these channels at a later time.
- a top trackform reinforcement preferably a mesh 32, rail support reinforcement 30 and any other ducting requirements for signalling, stray current collection, drainage products and pipes etc. is put in place.
- each pair of rails 34, forming a track is supported in this example by the "top down" rail construction method by using Gauge Support Frames (GSF's) 36 which are stabilised laterally by fixing the GSF to a thread (see Figure 8) cast into the troughs 22 at nominal centres (say every 500mm for maximum flexibility).
- GSF's Gauge Support Frames
- All of the mesh 28, 30, 32 is welded together and . is also used as the primary stray current collection system. At this time the mesh is spaced 28, 30, 32 as required, to provide reinforcement cover. It will be appreciated that the rails (or formed channels for the rails) will be checked for line and level at this time.
- the GSF's 36 each have a pair of prongs 40 which extend into the and cooperate with the mesh layers, whilst the rails are suspended by the GSF's.
- prongs 40 which extend into the and cooperate with the mesh layers, whilst the rails are suspended by the GSF's.
- ducting, drainage 3tc. will be set to position at this time, prior to pouring the trackform concrete.
- GSF This construction method (i.e. GSF) is state of the art, but a conventional process for trackwork specialists, and will therefore not be described in any more detail.
- the drainage boxes 31 will be linked to the existing drainage system provided by the drainage gulleys 16 and associated carrier drains 18 (as illustrated in Figure 4).
- Concrete shoulders 44 can then be cast level with the top of the rails. These are not essential, and could be replaced by a full width concrete finish, Pre-Cast Modular Block finish, or a bituminous surface laid adjacent to the rail. It is often advisable to expose the aggregate contained within the concrete to attain as high a skid resistance value as is possible. It is further advisable to colour the concrete to match aesthetically the surrounding road surface, or alternatively make the rails "stand out”.
- PSV values must satisfy the requirements stipulated by the DMRB and due care and attention must be given to ensure that the PSV of the different materials is as close to each other as possible, thus mitigating possible highway vehicle differential skid resistance issues.
- ducting trough 22 need not provide housing of the electrical cables but utilised for construction purposes.
- the trough 22 may be a support member providing formwork or support for the GSF's as described above.
- an exemplary embodiment of the ducting trough 22 is made up of a plurality of ducting sections 50, each defining channels 24, 26 running therethrough.
- Each section 50 has a built-in radius at opposing ends thereof, for example, as illustrated in Figure 6 or alternatively Figure 7, such that the sections fit together snugly, even around bends (in both the horizontal and vertical planes), and can, therefore, be articulated as illustrated in Figure 9.
- Each trough section 50 is made of concrete, reinforced by steel mesh 52 as shown in Figure 10.
- Metal bars 54 may be embedded in, and extend outward of, each section 50. Bars 54 can be used as fixities for convenient lifting or craning of each section 50 into position.
- a pair of threads 56 may be cast into the top of each section 50 for use in stabilising the gauge support frame (as explained above). It will be appreciated that the configuration of each trough section 50 according to this exemplary embodiment of the invention provides no water paths or construction joints, such that it acts as a Faraday cage to prevent, or at least minimise, stray current.
- the trough section 50 having a removable cover 60 may be provided to enable convenient placing of, sight of and access to the cables in the channels 24, 26.
- this provides, for example, a convenient way for maintenance workers to measure stray current at specific points along the track.
- the cover 60 may comprise a reinforced concrete slab housed within a steel tray 62 which is bolted on the top of the trough section 50. The cover may be removably held in place by a number of anti-vandal bolts 64.
- the high voltage cables housed in channels 26 of the ducting trough 22 are connected to feeder poles 70 for carrying current back to the sub-station.
- the feeder poles 70 are provided at spaced apart intervals along the train line.
- a cantilevered structure 72 provided to the side of the track may be provided to carry each feeder pole 70. This eliminates the need for deep excavation for this purpose.
- each pair of rails 34 is supported top down by a gauge support frame (GSF) 36 which is stabilised by a respective thread cast into the top of the trough 22.
- GSF gauge support frame
- a pair of GSF's 36 are provided at spaced apart intervals along the length of track path. All of the mesh is then welded together and spaced as required. It will be appreciated that the position of the rails 34 may be needed to be checked at this stage before they are permanently fixed.
- the GSF's 36 each have a pair of prongs 40 which extend into and co-operate with the mesh layers 28, 32, while the rails 34 are suspended above the bottom of the draining boxes 30 by the bracket-like members 42 at each end of the GSF 36. This is a conventional process and will not be described in any more detail.
- the present invention relates to a design and construction method for providing a trackform encompassing a holistic design and associated construction method, taking into consideration ease of construction, operation, maintenance and demolition.
- the design and associated construction method is a fully integrated multi-disciplinary engineering solution concerning, civil, rail, electrical and mechanical and signalling resulting in a safe, easily maintainable operational rail system.
- the rail system is however equally applicable to all other forms of rail design and construction. These include without excluding others; segregated running, tram, metro, light rail, heavy rail, high-speed rail and freight rail system. This rail system can be applied to all aspects of rail design and construction; for example, at grade, within a tunnel, running with a highway or elevated etc.
