The previous average speed jobbies were forward facing so didn't get the rear plate...
The new ones are super fangled rear facing & seem to have a small aireal on the top which I assume is some sort of communication device type thing...
Also previously the two cameras after the bridge were never live as there was a dispute with the railway bods not allowing the cables to be laid...Not needed now...So you have to assume that it is now live...However the last camera post by the port seems to have gone...
