This project will completely depend on what safety regulations will allow.
Translink would save money if they are only required to have 2-3 people at each station, instead of over a dozen drivers. not to mention the electric bill
would be must less then the current diesel bill.

The downsides are if they are required to have an attendant in each car that will kill the project right off the bat. The other downside I can see is it's not scalable, you can't add capacity during rush hours or take it away during quiet periods.
