Default Filling track gaps

Hi,

Because I had to cut some track with a Dremel to create insulated gaps I now have some rather large gaps. I can't lift the track so is there a recommended way of filling those gaps with something like epoxy or .....?

I'm using 009 Peco track so it's a bit fiddly

Thanks

David

When laying track one should always leave a gap between rail joints. This is to allow for expansion and contraction between winter and summer. Especially if layed out is in shed garage loft where it will be effected by extremes of temperature.
I use an old credit card gap between my rails. I think that is common method used by lot of modelers..............John

Understood. but these gaps are too big for small-wheeled rolling stock. I need to fill them at least partly. Layout is not subject to extremes of temperature, it's in our club room which is cool in summer and heated during the winter.

If the gaps are that big perhaps you should replace the track. I know you said you can't lift it but in reality any track can be lifted and replaced.

Technically I could lift it but they are close to a baseboard join so I'd have to unsolder from the paxolin, remove all the feeds, remove the frog polarity wire, remove the point motors and then lift the track (two turnouts) - way too much work. I'm reading elsewhere that epoxy (JB Weld e.g.) works well - anyone done this?

What sort of gap have you got? I've just cut a bit of rail about 1.5mm long off with my xuron track cutters and the track profile is good enough to glue into a gap (it's not distorted out of shape)

That works - but I need insulated gaps so rail won't work

I recon you could glue in a section of rail with a gap at each end so it was insulated - but then again it's not me trying to do it

Don't think I'd rely on the glue for permanent insulation.

Consensus appears to be epoxy type glues and trim or plastic pieces cut & glued and trimmed later.

We'll see

Oh well, you seem intent on bodging it - I'll leave you to it.
