Trackside 3D's Cable Trunking Systems can be used as a working cable routing system or to cosmetically enhanced your layout.
The cable trunking systems are scaled down to match Network Rail RT/E/PS/0013 concrete cable trough
dimensional specifications. These standards are compatible with previous British Rail specifications. These
products can be placed on any era layout requiring concrete cable troughs.
Our concrete cable trough system is comprised of trough and lid sections. The trough sections come in a variety of sizes to match the prototype. The trough sections are designed to be fixed directly to the baseboard with the lids placed on top. Then add ballast or other scenery leaving the appropriate amount of the trough exposed on the surface. Trough sections are available as straight, tee and curved pieces.
Trough straight sections come in single piece sections and ten piece sections. Single piece sections are available with scale and overside cable routing holes. Straight pieces with cable routing holes come with low profile lids. These lids are designed to increase cable capacity in the troughs but can be more challenging to install due to a smaller lip.
The concrete cable trough system is in service throughout the UK Network Rail infrastructure examples include Channel Tunnel Rail Link and West Coast Main Line. The concrete cable trough system is also installed for light rail and underground systems at Glasgow, Nottingham, Manchester, Sheffield, Newcastle and Birmingham.
Concrete Cable Trough systems are in widespread use throughout the UK Rail infrastructure. They are used to route power, fibre optic, pneumatic and rail cables. Our 3D models were constructed from the Network Rail RT/E/PS/0013 standard and scaling the dimensions to OO scale. The scaled versions were then compared to a number of manufacturers technical specifications for accuracy. Both the inner and outer trough dimensions are scaled to match the prototype. The concrete cable troughs are installed in 1m sections, typically placed alongside the track in a trench dug for the troughs. Concrete cable troughs have knock-outs for running cables out of the trough. Cables are run to other equipment such as relay or location cases, point machines, signals and so on. The Network Rail specification provides the following standard sizes, the dimensions below are full scale internal widths. C1.6 is a smaller depth, C1.8 and C1.49 offer larger depths while the others have the same depth.
- C1.6 100mm
- C1.7 130mm
- C1.8 150mm
- C1.9 190mm
- C1.10 250mm
- C1.29 350mm
- C1.43 350mm
Cable Trough System
The Trackside 3D concrete cable trough system is designed to match the specifications listed above at OO scale. The system consists of the trough base and trough lid. We provide straight trough bases in one piece sections, a scaled version of the 1m troughs. These bases are available without cable routing holes, with cable routing holes on one side and with cable routing holes on both sides. The bases are also available in longer 2x, 4x, 6x, 8x and 10x sections to make it easier to install long sections of trunking. All of our cable trough products come with easy fit lids, these lids have a slightly deeper lip for easy installation. Our curved, tee and straight troughs with cable routing holes, also come with low profile lids and easy fit lids with cable routing holes. These are designed for using the cable troughs to route cables, the low profile lids increase cable capacity but can make installation a little more fiddly. The low profile lids and easy fit lids are design considerations that are not quite to scale but are necessary to make the product enjoyable.
Trackside 3D provides the necessary components for fully functional cable routing from C1.6 through to C1.43. The capacity and practical use of the cable troughs will depend on the number and gauge of the wire. The products were designed with 22 AWG (0.6438mm) or smaller in mind, but can be used with large cables sizes. We recommend using C1.43 or C1.8 with 22 AWG (0.6438mm) wire for best results. Due to the smaller depth of the other sizes, you will need to use 24 AWG (0.51mm) through the cable routing holes. These work well for signals and sensors.
The deeper C1.43 and C1.8 cable troughs can easily accommodate multiple 22 AWG wires (0.6438mm) but only one wire through the cable routing holes on the straight trough sections. Due to the smaller depth, the other sizes require 24 AWG (0.51mm) or smaller wire in order to route cables through the cable routing holes. Some of the smaller depths will accommodate one or more 22 AWG wires when the low profile lids are used. If you wish to use the smaller depth cable troughs with 22 AWG wire, you will need to either use C1.8 or C1.43 straight cable troughs with cable routing holes at the points where you want to run cables in/out of the trough or connect 24 AWG or smaller wire from the 22 AWG wire when exiting the trough. We recommend using solid core wire in the trough as it makes running cable easier, but stranded wire also works.
Trackside 3D recommends installing the cable trough bases directly to the baseboard. These can be temporarily put into place with blue tac, tacky wax or double sided tape. Once you have determined the final cable path, the troughs should be glued into place and painted. We recommend painting the cable troughs with your preferred enamel model paint. The prototype troughs are made from concrete. Trackside 3D prints the troughs using grey PLA then paints with a grey-white blend on enamel paints. If you are planning to use the cable troughs for running cables, we recommend adding the cables at this point. Once the cables have been installed and tested (signals, point motors, train detection), you can add the lids to the system. If you are using the troughs for cosmetic purposes only, you can glue the lids in place. We recommend using blue tac rather than gluing the lids if are routing cables. This makes it easier to remove the lids and fix cabling at a future time. Once the lids are in place, we recommend painting the lids and then adding ballast leaving the desired amount of the concrete trough exposed. When gluing the ballast, if you are using blue tack to secure the lids in place with cables, be careful not to glue the lids in place. Once the ballast has dried, we recommend weathering the cable troughs with your preferred weathering method (air brush, spray paint or powders).
