Diesels would be unlikely on the Rosewood trains as there are no run round
facilities at Rosewood. Either a DEL would be required each end or the
trains would have to run to Grandchester to run round. QR very cleverly
built both crossovers at the Brisbane end of Rosewood. Rail motors may be
more likely. There are at least 5 x 2000 class rail motors in service now
including one centre unit. I understand that these are intended for use
during isolations as that many are not needed for the Yeerongpilly-Corinda
shuttles.
