I was in Vancouver late last summer and tried out there Compass card. Very slick system seemed to work ok, I especially liked the electronic gates at the Skytrain stations.
If Calgary Transit is going to look at a new EFC they should also invest money into Ctrain stations with some sort of electronic gate system like Vancouver.
Also, I think it's time for Calgary Transit to dump the free fare zone downtown during rush hour and just have the free service during non-rush and weekends only. So many people live downtown now that it would help with revenue to fund this thing...
Fare evasion is such a problem out here and should be treated more like a crime even though it is nobody really realizes that.
