I wonder if this new 'voegloos' stuff is quite as good at absorbing heat as the 'kedeng kedeng' ones though :) I don't remember that in the 80s/90s there were such concerns and I had family working on railway maintenance. The climate problem wasn't as big back then but we had some scorching summers too. Instead the autumn was the all hands on deck period with leaves on the tracks and later in the autumn snow freezing the switches.
