Class 156
FYI: The original Class 156 units are actually all in subclass /0; they just have 1564xx and 1565xx numbers they'd match the 524xx/525xx and 574xx/575xx vehicle number ranges. Otherwise you'd have something like happened with the Pacers, where 144001 is made up of vehicles 55801 and 55824. XAM2175 (T) 22:16, 14 January 2023 (UTC)
