I've heard that some years ago, the Victorian Railways (specifically Melbourne metropolitan) used to have split (broken) shifts, but abolished them for, I believe, fatigue reasons.
Can anyone provide more information about what year they were abolished, what was the lead up to the change, and how were the peaks catered for with the removal of the broken shifts? Was standby time used to make up the time in other "straight" shifts that only worked one of the peaks into a full 8-hour shift? Any information would be much appreciated. Currently I work in an area of public transport that still has these types of shifts.
