I noticed on the Great BritainXVI WCR use a full rake of wine coaches.Did they fit Cask or did they repainted the Riviera stock
WCR already had a full set of air conditioned Mark 2 coaches in their maroon livery, which is what has generally worked for RTC.
I think the set on the Great Britain is formed of 9539, 3334, 3336, 6724, 3431, 3392, 1961, 3395, 3352.
9539 was formerly in ScotRail colours when with Riviera. 3334 and 3336 were Riviera coaches but I think in Anglia colours rather than blue-grey. The rest were already with WCR.
