(07 Jan 2018, 4:34 pm)S813 FVK wrote 706 has gained a rear advertisement for contactless payment (identical to that on 641-646). No idea if the other Solos/SRs have followed, but here's me hoping that 708 was fitted with a tagline while they were there.
It wasn't as the fitters didn't have one of the taglines with them when doing those rear adverts, but is due to be fitted in the next round of 'snags' at Stanley. Should be fitted within the next two weeks, along with other members of the fleet with missing branding.
