Railwayscenics currently supply one of the largest ranges of electrical wire specifically for railway modellers and hobbyists. We supply a wide range of electrical cable in various colours, sizes and lengths which can be found by clicking here.

All cable sizes are available in black, blue, brown, green, grey, orange, pink, red, purple, white and yellow, apart from the 55/0.1 flexible cable that is only available in black, blue, green, red, white and yellow and the 30/0.25 which is currently only available in black and red.

All of our electrical cable is manufactured to DEF61-12 Part 6 Type 2/3 and BS4808 part 2 standards apart from the tri-rated cables which are made to BS 6746.

We offer wire in 2m, 5m and 10m lengths, or on a complete 100m reels. All are listed separately in our store. Where possible measured lengths of layout wire is sent in one continuous length, but this is not always possible. If you require larger quantities than those listed in our store, please either telephone or use the contact us form and we will be pleased to supply you with a competitive price.

If you require a sample of the wire you require please order a 2m length of your desired wire.

Wire sizes
The method of describing the size of our electrical wire confuses some people. Just by way of clarification the first number refers to the number of strands within each multi-strand wire and the second number is the diameter of each strand. So a 7/0.2 wire will have 7 strands of 0.2 wire. We also use a mm sq dimension and also an approx AWG, which is mainly used in America and the mm sq allows a comparison of the copper core area within the cable.

Try to avoid using solid cored wires on your layout as they will break if bent backwards and forwards too many times. Solid cored wire can be used where the wire needs to hold its shape, and also for soldered DCC bus dropper wires as long as the bus wire is fully supported along its length.

Wire Insulation
The wires that we sell come with two main types of outer insulation. They are:
PVC: The advantage of PVC wire is that it is adequate for most situations and the ends are easy to strip to make connections. However it can melt or in severe cases it can burn when it becomes hot. Also when it is cold, the PVC becomes brittle and can crack if bent.

PTFE wire: PTFE wire is far more expensive than PVC coated wire. The PTFE insulation is more robust, and can be used over a much wider range of temperatures. However it is much more expensive and it is also much more difficult to strip to expose the bare copper wire for making connections or soldering.

7/0.079mm(0.03mm sq) 32 AWG
A general purpose ultra flexible and ultra fine stranded wire supplied in 1 metre coils that can be used for wiring DCC decoders and power leads between tenders and locomotives. Due to the very fine nature of this cable it can also be used as lighting wire where wires need to be insulated in lamp posts.
