410 Winchfield 6 November 1991

In late 1991, two of the surviving Class 438 4-TC trailer sets were refurbished and repainted into 1960s style all over blue livery for use on Premier Charter specials. A lot of the time the two units (410 & 417) operated together, but here we see 410 being pushed into Winchfield station on its own on 6 November 1991 by 33116. This was just a few das after the repainted units had entered traffic. Judging by the platform activity, this is clearly some sort of charter train, but unfortunately I have no further details. Any information would be greatly appreciated.
