Wasn't there a reversal station at or near Urangan in Queensland?
Yes there was.
Maryborough (Qld) was a reversing station until a fork was built at Baddow. Roma Street would have been a reversing station from 1882 to about 1890, but it's unlikely there were ever any trains that didn't
terminate there. There was a reversing movement for trains between Ipswich and Bundamba, from 1874 until Ipswich station was relocated from what is now the North Ipswich branch to the current location, in 1887. Toowoomba was a reversing station for Brisbane to Roma/Charleville/Cunnamulla/etc trains (and might be again), and also Brisbane to Warwick/etc trains until the direct line through Drayton was opened. Bowen was a reversing station at some stage. So were Cloncurry and Townsville.
Burnie (Tas) would have been a reversing station if there were ever trains between east and south. Irishtown was a reversing station, though there was a fork that bypassed it.
Clifton Hill (Vic) was a reversing station until the direct line from Jolimont was opened. Sale was a reversing station. Also Beech Forest, although there was a balloon loop at the end of the line.
