Anyone know what 3 Wiltax Metrobuses were doing heading from Morden
area to the A3 southbound would have been up to? So rare to see
Metrobuses these days. They looked pretty good, still had exit only
doors (I gather some have had exit doors replaced with a window as exit
only doors not essential away from London) and sounded in great form!

I presume they are heading off to do a rail replacement somewhere but
feel free to advise!
