I should add that, yes, I have damaged a few points, in which they go straight in the bin or sold online as "damaged, spares or repair". Most track, especially plain flexible (which is most of my layout) gets re-used without any problems.
Ok thanks. I use standard Hornby track, not flexible track, but I will try the hot water trick. The layout is in the garage, so spill is not an issue. My only other concern is the pins. I did ensure they were quite close to the track, so I am not sure how easily they will come out. But I will try!
