If it is the same kind of foam tape that I am familiar with, used to
affix hooks to walls, it will be highly resistant to tensile loads and
will snap loose easily with shear loads.  e.g. Hooks can be removed by
twisting, but not by pulling.

3M make an acrylic foam double sided tape which may be suitable. It is
available in various widths and thickness from the major hardware stores
like Bunnings or Blackwoods. I would suggest you try one about 12-15mm wide,
doubled up side by side to give a suitable overall width and a thickness of
3 or 5mm. Once unrolled, follow your track centreline with the exposed
sticky side and then lay the other piece following the first contour to give
an overall width of 25-30mm whatever size you choose...a bit like laying a
cork underlay. Then all you have to do is peel away the proctective overlay
and lay track. Do this lightly to achieve proper alignment before pressing
the track firmly into the tape as it may be difficult to pull up and re-lay
track. The rail will expand and contract according to temperature conditions
and the tape should compensate, particularily if you have an S bend or large
radii
Hope this helps...Ted
