50030 Repulse thrashes up the mainline at South Moreton on 8 November 1986 with the 1V52 10:10 Birmingham New Street to Paddington service. This explains the predominance of Mk 2 stock in the formation, and especially the inclusion of an InterCity liveried vehicle. The more common Oxford trains would generally at this time have been formed of Mk 1 stock, although at this time blue & grey was still the norm livery wise, despite Network SouthEast having been launched during the summer.
