When that kit fails to report, it is removed from the list of allowed vehicles and then becomes subject to fines. This has recently started to be fully enforced by Newcastle City.
The issue unfortunately is that repair and replacement of the reporting kit is not fast, so that is why some buses are okay and some aren't. The bus might be perfectly fine, but if it's not communicating, it's not allowed in the CAZ.
Slatyford’s 19385 and 19386 have suffered the same fate and are not allowed in the city centre now as well. What do we think they plan is with them then, can’t go on the 6/7 so Walkergate for the 18? Or maybe Sunderland swap with 19440/444?
