The Saltwell Park Versas will be used on the M2/M3, There zero need for them on the W5/W6 as the service is barely used during the day, minus peak times when it does fill up.
Chris White confirmed to me on FLICKR that the 61 is now Simplicity Branded along with the 42. TBF I don't see the point in the Streetlites replacing the Versas on the 60, work quite well to my knowledge of using the service.Which is why I think the Streetlites may end up on the 39.
Just have to wait and see aren't we.
