A time validity on bus fares would also help with the problem you get
with
buses failing or turning short of their destination. No need to mess
around
with transfer tickets, just touch in again and don't get charged. Let's
make it a nice generous figure like 90 minutes though and if people can
make
return trips in that time and only get charged once then good luck to
them.


This is already the situation on the Croydon trams. A second touch-in within
80 minutes is free.
This is meant to cater for changes of tram, or changes to/from the feeder
buses, but also permits quick return trips at a rate of 40p each way. 80
minutes is easily long enough to get from one end of one the branches of the
system to any other, do some light shopping, and set off back again.
This facility is not all that well publicised ..
