The trackbed is also where most of the suspension for a train comes from. More so in the days of steam where the axles of the steam locomotive had very limited freedom of movement. In the UK the gap between lengths of track is 3/8in (9.5mm).
Good video. One more (9th on your list) usage of tracks is to aid signaling. tracks are segmented electrically. One rail carries a low voltage while the other rail is grounded. The axles of the train using that segment short-circuit the rails and causing a relay to trip and indicate the presence of a train on that rail segment. Please correct me but I think they are being replaced by axle counters. Thanks.
