Publish the number of trains cancelled by route, or stations missed on route.
Why is this important?
Cancellations and significant lateness (CASL) is not a regulated measure in Scotland like elsewhere in the UK. Instead companies like Scotrail cite PPM - trains arriving within 5 minutes of their scheduled time.
What this doesn't reveal is the transport routes in Scotland blighted by cancelled trains or missed stops which is more inconvenient to passengers than a train 5 minutes late.
The CASL statistic would highlight:
Cancellations at origin
Cancellations en route
Change of origination station
Failure to stop at a scheduled station
Significantly late trains (late by 30 mins or more)
