The Scottish government decided to split the sleeper contract from the main ScotRail franchise after a recent review of transport policy.
Today's rule still allows them to "split" the sleeper berth period, but one of the splits must be 8 hours long and the remaining 2 hours do not stop the 14-hour on-duty period.
When Sleeper split up in 1998, Britpop was sort of falling apart.
Louise Wener, who split her band Sleeper in 1998, says it's the result of what a group stands for in people's lives.
A report by contractor Tube Lines said the faults included split and rotten sleepers.
Visitors at the centre are evenly split between rough-sleepers, people in temporary accommodation and those who have recently been housed but are struggling to cope with the demands of a normal lifestyle.
The rule of the sector is mostly split among four houses, each named after the sleeper ship that brought them to the system.
Later, an added exception for trucks equipped with sleeper berths meant drivers were allowed to "split" their 8-hour off-duty time into two parts.
