628 is on 39s. Got to Grangetown about 10 mins ago bound for Doxford Park.
If any of the OK Expressway branded vehicles were to stay in that livery, it would have been 5229. That vehicle was the spare one which was branded as the centenary vehicle for OK Motor Services. As we all know, now Northern.
From my small amount of experience on the 74 etc, people use the 10 rather than the 74 if they are wanting to do the full NCL to HEX stretch. Who wouldn't (other than elderly people perhaps)? Plug sockets, WiFi... It provides most customers with what they'd want travelling for that amount of time.
