The material the rail is made from will determine the amount of expansion.
Different materials will expand at differing rates.

You might want to visually inspect those "former" gaps on a warm/hot day. If
the ends of the rails now touch, that would be a good place to cut a new larger
gap before the pressure builds up and leads to a kink.
Question: In the real world, how do RRs prevent heat kinks when welded rail is
used for l-o-n-g stretches of track? With welded rail, there are no slipping
expansion joints -- or are there?
