Laying the Track

Detailed 'how to build it' guides are available from each manufacturer along with all the components. One of the advantages of P4 is that all the components are very close to scale, and thus it is possible to build any formation of points and crossings used on the prototype. Whatever construction system is used, the assembly will be built with the aid of a drawing, usually called a 'template'. This allows the formation to be built on the workbench in good lighting and to be transferred to its final location on the layout once complete. Templates are available for most common track formations from the component suppliers. They can be also be created and printed at home, using a computer program such as 'Templot', which allows you to design your track formation on the computer and then print out templates for each element as required.

Once built, the track and points need to be laid. Underlay to represent the trackbed is available in convenient ready-cut strips of cork sheet or in closed cell foam. Alternatively the modeller can purchase larger sheets and cut to the size required. The track should be glued to the underlay using a diluted PVA glue or similar; ballast may be added at the same time or can be added later if preferred.

Additional detailing

Components are available from a number of manufacturers, covering such items as dummy point rodding and operating cranks, signal pulley wheels, facing point locks, third and fourth rail, and so on. The photo on the right shows the two varieties of conductor rail supports for third and fourth rail prototypes.

Components to make up these conductor rail supports for London Underground and ex-BR Southern Region systems are available from the Scalefour Society.
