Red & White N475 (GHB687N) in Cardiff Bus Station, displaying a 'Leyland National peculiarity' - the tendency for destination blinds to slip. Of course, it may be that the driver had not positioned the blind correctly, but the slippage was a known problem, that sometimes confused passengers if it slipped too far! The 175 service operated between Cardiff and Hirwaun/Neath or Swansea via Aberdare, and the staff at Aberdare had already agreed to one-person-operation of large single deckers by 1975, unlike their colleagues in the Monmouthshire valleys who would not consider OPO for any vehicle with more than 45 seats.
