Hi,
Does anyone know if phone or thermostat wire is a suitable or (more
importantly) safe replacement for the 9v train wire? If not, anyone know
what I can use? I am running 45 feet of track in a loop and I want to run
additional wires from the transformer to boost the current at other spots on
the track.
Thanks,
Tom

it’s perfectly safe to use and model railroaders used it quite a bit in the
50’s however i would suggest using braided wire instead of solid core. from
what i’m told braided wire has less DC voltage loss “or was it less
resistance” over a distance than solid core. the oppisite is the case for AC.
Either way i would use something like speaker wire instead of phone/thermostat
wire.

First off, I use speaker wire. It’s ideal for the apllication. I’ve even popped
open the 9v connectors, and replaced the wire for longer runs. It’s also
polorized, so I can intentionally create straight thrue or cross cables without
haveing to get out my meter.
As for resistance issues. You have it backwards. DC runs just fine in a solid
wire. Whereas AC sees more resistance in a solid wire. It’s called the skin
effect

. But, for the size wire that is used in homes and smaller, the effect is
negligable.
