tracklaying

Hello railroad modellers,
my layout is placed in an unheated side building and is subjected to temperature variations. This causes a little troubles regarding railgaps. What will be a good non conducting material to use filling the gaps?
Also I need a good picture showing how the cables for the traction motors are placed on a C44 - 9W. Any help here?

as for the insulated sections of track - you can use either insulating rail joiners (for between sections of track); or if you’re cutting the gaps - like for a turnout - you could use styrene.

I have the same problem. For insulated joints (behind turnout frogs and for signal block isolation) I use commercial insulated rail joiners, allowing some extra gap space if I’m laying track in cool weather. For uninsulated joints I use regular rail joiners, again leaving extra space, and then solder jumpers around the joiners.

Come August, and 115-degree afternoon temperatures, I’ll find out if I left space enough.

Thank you friends for your reply,
I use Peco code 100 track and Peco insulated railjoiners.The small tap on these joiners do not reach the top of the rails. Combined with contraction in cold weather that leaves an excessive space or gap. I think I will try epoxy and see what happends when summer returns.
Still no ideas where to find a good left side picture of a C44 - 9W so I can see how the cables for the tractionmotors are located.
