43015 passes the site of Honeybourne South Loop Junction and starts the long climb up Campden Bank with the 13:14 Great Malvern to Paddington 'Cotswold & Malvern Express' on 25 April 1987. At the time this and the earlier balancing working were the only HST services on the Cotswold Line. However, this was all to change just a couple of weeks later when HSTs took over from Class 47s & 50s on the morning and evening peak trains.
