Lucky double feature in Rosewood

Today I got quite lucky at Rosewood station. I had walked onto the platform to set up for the train that I had spotted waiting west of town, when I heard a horn, and turned around to see a train heading the other way. I had just enough time to start filming that train, consisting of 2313D and 2497H, both in varying degrees of faded Eagle livery, barreling through the station at full operational speed, also not something I get every day. Then I headed over to the other side to wait for the second train train, and imagine my joy when I saw that it was led by 2702 in its Indigenous livery. I have not often seen that loco in the wild, and today it gave some extra smoke signals too. 2320D was the second loco in that train. If someone can tell me why there's always that massive clanging coming from the wagons towards the end of the train, hit me up in the comments :D
